Often when a company is acquired, its users celebrate all the new resources the site will have, and congratulate the founders on their success. But this isn't the way it's shaping up on FriendFeed, where many users saw FriendFeed as a better alternative to Facebook, and express the very real fear that the FriendFeed community will be destroyed.
Unusually for an acquisition announcement, around 50% of comments on the official FriendFeed announcement of the deal are negative, with users expressing concerns about the sites being merged, about the FriendFeed community going mainstream and the lack of similarities between the two communities.
Their fears are probably well-founded: there would be little point for Facebook to keep FriendFeed as a standalone site with so many overlapping features. Most likely, Facebook will simply make use of FriendFeed's best features on its own site, including the popular FriendFeed API.
For the record, we spoke to FriendFeed founder Paul Buchheit, who said there are no immediate plans to close FriendFeed.
