Yahoo’s recent announcement of its intent to purchase Tumblr has brought out the virtual fangs. Lets take a look at some of the more creative responses.

Tumblr users are passionate and are worried about what will happen to their platform. Is that passion enough to keep their pages safe from being “Yahoo’ed?” If the deal goes down, Tumblr as you and I once knew it, may be done. Though the spin is that Yahoo will not screw it up, it’s tough to think that advertising, for example, does not become a focal point of the pages.

The evolution of a “social” start-up usually takes two paths, maybe three. There’s the fledgling, cash strapped version that dies the slow death never fully realizing its potential. There’s the doomed from the start version that never gets the funding it needs or just may be a good idea poorly executed and then there’s the Flickr, Posterous, Instagram, Tumblr variety. The types that get bought and are altered forever. Never fully being what they once were and not resembling what they once used to be in their newest and improved iteration.

Picture the arc of the  social startup looking something like this…

Lot’s of hope and promise, a grand show, a fitting finale that everyone loves and then it’s gone. Is that what lies ahead for Tumblr? How about Facebook?
