i’ve written a post on search engine land explaining why sharing content is a good idea, and laying down some guidelines to help you share without overwhelming your friends.
no feature that i can recall in recent memory has polarized the social news sphere more than the ability to mass-alert stories to other users for immediate votes. stumbleUpon has the “send to” feature, propeller has “site-mail” and digg has “shouts.” as i’ve said before, the feature is a great one in principle but can be a horrible one in practice. as with any tool you give to people, half your job is to educate them on how to use the feature and set some guidelines so that it’s not abused.
learn how to use the feature without annoying anyone.
