Overlinked

There's been a spate of new apps out that use twitter for promotion of certain activities (like visiting a brick and mortar store).  If you haven't heard about FourSquare, then you should check them out.  But now that Yelp is doing something very much like FourSquare, I wonder how many websites will follow in this vein.  If Yelp's done it, then CitySearch, Google Local, Yahoo Local, and every newspaper out there may wake up to the viability of this type of application.  Urging users/consumers to "tweet out" their patronage of every place they visit. If this happens, then we'll see a mjaor backlash against these types of services. 

Already Simon Sage said on IntoMobile that he'd unfollow "a whole lot of people".  My sentiments exactly. There needs to be a way to filter the "types" of messages received.  Linked in has this problem which I've recently commented on.  But really all major social networks could take a lesson from Facebook which allows blocking of certain "application" based messages.  So having discovered this, I no longer get Mafia Wars Facebook status updates (thank heavens!).

Twitter, Facebook (and even maybe SMS/Cell providers) should take note of the benefits of filters.
