Rumor: Social bookmarking site Mister Wong acquires Lifestream.fm?

So maybe today's social-media M&A gossip of the day involves two moderately-to-extremely minor players in the space, but hey, we can't always have juicy Facebook news. Mashable reported Tuesday that Mister Wong, a social bookmarking service, has acquired Lifestream.fm, a small social site that (as its name would suggest) aggregates data from multiple social-networking accounts into a single "lifestream."

No background is provided other than the report that the acquisition was made for an undisclosed amount.

Mister Wong, a European site, is a sort of cross between Delicious and StumbleUpon, generating recommendations based on the bookmarks a user has flagged. As the puzzled Mashable writer points out, there doesn't seem to be an immediate correlation between the two that would explain an acquisition.

Representatives from Mister Wong were not immediately available for comment.
