Is Google pulling Social Search experiment after just a few weeks?
In the last hour I - and others - have been seen messages from Google stating that the Social Search experiment/Google Labs option is no longer available.
This is a search for [bigmouthmedia bjornis] which clearly shows the removal notice. The text says; "The experiment you're trying to access is no longer available. Go to experiments overview"
Google launched Social Search on the 26th of October, that's less than a month ago.
It seems most likely that this isn't a planned reduction of the social search test. It may well just be the sort of hiccup you should expect when you take part in a Google Labs experiment.
It is possible, though, that for whatever reason Google now has enough data (perhaps loads more people in the experiment than usual) and is now needing to wind it down.
