After Yahoo! announced the purchase of micro-blogger Tumblr, WordPress saw a spike in imports to WP from Tumblr. Matt Mullenweg’s blog:
The relationship between WordPress and Tumblr has always been pretty friendly: Tumblr’s own blog used to be on WP, WordPress.com supports Tumblr as a Publicize option alongside Twitter and Facebook, our Akismet team sends them daily emails of splogs on the service, and there’s healthy import and export traffic both ways. (Imports have actually spiked on the rumors even though it’s Sunday: normally we import 400-600 posts an hour from Tumblr, last hour it was over 72,000.)
It will be even more interesting to see what Yahoo! does with Tumblr.
