I'm sure I'm very late in noticing this, but just after I saw Technorati's relaunch as a memetracker, I noticed that IceRocket is starting to look different, with a new (to me) looking front page, ranked video, movies and news. According to Compete, Technorati's shift looks like it may have resulted in an upswing of visitors, while IceRocket is still languishing.
Of course, searching in blogs for mentions of an IceRocket redesign is hopeless. A search on IceRocket just brings up spam, a search on Technorati brings up anything with an IceRocket tag (even a search for "icerocket new design -"icerocket tags"" doesn't seem to help). Perhaps no-one noticed.
Interestingly, a search on Google unearthed this:
None of the Twitter search engines appear to have any posts indexed mentioning IceRocket (Twitter is hard to crawl comprehensively).
