Recently I read somewhere that the demise of Twitter is imminent and all anyone wants to talk about anymore is Foursquare and Gowalla , 2 shiny new LBS based companies that are reeling in new users by the bushel. Sure I’ll talk about and use Gowalla and Foursquare, but that doesn’t mean that Twitter is no longer relevant though. In fact what this  simply means is that those 2 aforementioned companies have merely carved out a niche for themselves in a space that Twitter doesn’t necessarily play in, though they have added an LBS type feature as of late.
