The press will attack Google, GOOG will drop
False. The press has been more critical of Google, poking at it occasionally on management, privacy issues, and the YouTube deal. But, there has been no major disillusionment or scandal, and the stock price has only gone higher.
Yahoo bets on community, buys more community startups, gets little benefit
True. Yahoo has bet heavily on community and social search (Yahoo Answers, My Web, del.icio.us), but success with these in the mainstream has been mixed. Yahoo acquired del.icio.us and Jumpcut. Yahoo has disappointed investors with their performance, leading to a major reorg recently.
Microsoft launches unsuccessful AdSense competitor
False. Microsoft launched adCenter, an AdWords competitor, but has not launched an AdSense competitor yet.
MSN Search will increase share
Very false. In fact, MSN Search share dropped substantially. I'll say it again, it really is remarkable how badly MSN Search is doing.
Microsoft will abandon Windows Live
False. What I meant by this prediction is that Microsoft could not maintain both the MSN and the Live brand, so they would choose MSN over an expensive effort to build a new Live brand. But that was wrong too. Microsoft is not abandoning the MSN brand or the Live brand; they are trying to build both brands, creating much confusion.
Mainstream will like tagging images and videos, but not documents
Mostly true. My Web 2.0, del.icio.us, and other apps for tagging documents do not seem to be attracting large audiences. Tagging images on Flickr and videos on YouTube seems reasonably popular, though, even for images and videos, it is not clear that large mainstream audiences widely have embraced the effort required to label things with tags.
Tagging sites will be assaulted by spam
False, at least at the level I was predicting. I thought Technorati, del.icio.us, and Flickr would be flooded with spammers labeling ads and other crap with arbitrary tags, hoping to attract clicks. Technorati and del.icio.us show some spam, but are not "assaulted" by an "influx of crap".
A spam robot will attack Wikipedia
False, but the part of this prediction that said that Wikipedia will "shut off anonymous edits and place other controls on changes" was at least partially true. As Nick Carr said, "the administrators adopted an 'official policy' of what they called ... 'semi-protection' to prevent 'vandals' ... from messing with their open encyclopedia." Moreover, as Eric Goldman argues, major spam attacks on Wikipedia may just be a matter of time.
Yahoo and MSN launch blog search, Technorati and Feedster lose share, Google Blog Search dominates
An impressive and more ambitious version of Google Q&A
False, at least not yet. I was expecting to see something really cool here, a product of the massive processing power of the Google cluster, but it did not happen. Though, I have to say, hints of good things to come seem to keep popping up in Peter Norvig's talks. Maybe this is just a matter of time.
A VC-fueled bubble around personalization
False. There has been interest and some funding for startups doing personalization and recommendations, but not at the absurd, frothy level I expected.
Google News adds recommendations, MSN/Yahoo experiment with personalization, all three expand in targeted advertising
Mostly true. Google News does have a widget that recommends news based on your reading history. AOL launched news recommendations in My AOL. Yahoo and MSN are both doing early experiments with behavioral targeted advertising, but have not done much elsewhere with implicit personalization.
Hype about mashups and APIs will fade
Mostly false, since there still is much hype, but there are signs of a growing backlash. See the updates at the bottom of this post.
eBay's business slows, eBay makes other acquisitions to acquire growth
Mostly true. eBay's growth has slowed. The expensive Skype deal seems to have tempered eBay's interests in additional acquisitions, but they did do a $2M acquisition of Meetup, $48M acquisition of Tradera, and a deal with Google.
Well, not such a good track record. About a third true or mostly true. Maybe I should put away my crystal ball?
Update: As John K pointed out in the comments, Microsoft adCenter is an AdWords competitor, not an AdSense competitor. Microsoft has not yet launched an AdSense competitor. Sorry, my mistake.
Update: I may have judged too soon on the lack of a backlash against APIs. Google very recently pulled their web search API, causing Dare Obasanjo to say:
One thing that is slowly becoming clear is that providers of data services would rather provide you their data in ways they can explicitly monetize (e.g. driving traffic to their social bookmarking site or showing their search ads) instead of letting you drain their resources for free no matter how much geek cred it gets them.That is not too far from what I said back in Nov 2005:
I keep hearing people talk about as if companies are creating web services because they just dream of setting all their data free. Sorry, folks, that isn't the reason.Update: I guess I also judged too soon when I said Technorati is doing surprisingly well against Google Blog Search. According to a Dec 28 article from Hitwise, the combined traffic of blogsearch.google.com and search.blogger.com is now about twice that of Technorati.
Companies offer web services to get free ideas, exploit free R&D, and discover promising talent. That's why the APIs are crippled with restrictions like no more than N hits a day, no commercial use, and no uptime or quality guarantees. They offer the APIs so people can build clever toys, the best of which the company will grab -- thank you very much -- and develop further on their own.
Update: Maybe I was just too early on the VC frenzy around personalization. VC Fred Wilson predicts that "the implicit web is going to start taking off in 2007" where the "implicit web", as Fred defines it, is using clickstream and other implicit information about preferences to do recommendations and personalization. Perhaps the frenzy will be in 2007, not 2006.
