Google's having a bit of a clear out, binning the stuff that failed or was absorbed into the Google+ behemoth. Gone are Wave, Gears, and Knoll, which join Buzz on the scrap heap of unloved Google failures.
You may have never heard of Knoll, which was a sort of Wikipedia competitor launched in 2007. Google's also killed off Bookmarks List, Friend Connect, Search Timeline and its Renewable Energy Cheaper than Coal (RE<C) project, all of which you'd be forgiven for not knowing of either. Google produces a fair few decent services -- I'm rather partial to Gmail, Google Maps and the old-style Google Reader -- but it also produces a lot of tat. Good to see it refocussing on the stuff that works and clearing out the stuff that simply doesn't. [Google via SlashGear]
