Early this morning Yahoo announced it would be acquiring Tumblr for $1.1 billion in cash – roughly a quarter of the purchase price Disney put up for Lucasfilm – and promised to "not screw it up." Naturally, there were some long-time users who were skeptical of the deal and decided to express their feelings. On Tumblr.

Yahoo CEO Marissa Mayer, in an apropos move, announced the deal on her own Tumblr with a post titled "Tumblr. + Yahoo! = !!" and a GIF of the "keep calm and carry on" meme, which naturally was the Tumblr community's cue to panic and freak out. No sooner had the deal been announced than users from the site's 100-plus-million blogs began to chime in with their thoughts.

"Do not distroy the fandoms. Please," implored one user. "So Yahoo bought Tumblr, which means it’s time to pack my bags and move on," laments another. "It’s been real good knowing you, Tumblr." Others, naturally, posted their own response GIFs, like the Simpsons logo mashup above which was posted with the caption "Enough said." And in the grand re-blogging tradition, a separate Tumblr has been established called Meltdowns About Yahoo Buying Tumblr to catalog the reaction posts. (Meta enough for you yet?)

But watching the "Yahoo buying Tumblr" hashtag on the site today has been both entertaining and a testament to the diverse community that lives on the microblogging site. Some worried about the loss of the fan communities on the site, others felt they themselves were being sold, and – yes – some worried what would happen to the porn.

So, do Tumblr's meme masters need to be worried? Maybe, maybe not. Some are pointing to Yahoo's poor handling of its Flickr as an example of what could lie in store for Tumblr. Yahoo's disastrous acquisition of the once-popular photo site, which Mat Honan called "a case study of what can go wrong when a nimble, innovative startup gets gobbled up by a behemoth that doesn't share its values" is surely on the minds of many Tumblr users.

But as Dan Gillmor, the founding director of Arizona State University's Knight Center for Digital Media Entrepreneurship told EW, the management team is different now than it was directly after the Flickr acquisition. Still, he added, "users always should be worried when a large public company buys a smaller innovator, because the record is not altogether positive in terms of the outcome.”

However, other cooler heads on Tumblr have pointed out the obvious fact that the world hasn't ended... yet.

"I love how Yahoo have actually stated that they don’t want to change the things that make tumblr great (a couple of those things being no ads and no sign-up fee) but you guys are all freaking out about how they’re going to completely fuck up tumblr and it won’t be the little safe haven the we all so desperately crave," wrote one user. "So why don’t we leave the freaking out until they’ve actually fucked something up? Okay?"
