Google+ does seem to be taking off very quickly. Or perhaps it's the fact that I hang out with geeks -and goth geeks at that- who may be more likely to be unhappy with the failings of Facebook (especially regarding privacy, etc) and willing to explore alternatives. In any case, in a couple of days I find that a substantial number of people I know are on G+ already, with more appearing all the time. For a clearly as yet somewhat experimental and unfinished product that is very impressive. It might not follow the fate of Googlewave after all. We'll see..
