Social-bookmarking service Diigo has acquired web-clipping service Furl for an undisclosed amount. Furl’s parent company, Looksmart, received stock for the company, which it bought in 2004. With the deal, Diigo buys a company that offers services similar to its own — users can save and annotate portions of or entire web pages and share them with friends — allowing it to bolser its offerings without spending any cash. Furl never quite took off like its competitor Delicious (formerly known as del.icio.us); it attracts about 100,000 unique monthly visitors, according to Quantcast.
The acquisition comes amid consolidation in the social-bookmarking space. Just a couple weeks ago, Yahoo (NSDQ: YHOO) recently announced it was shuttering one of its bookmarking sites, Myweb, to focus on Delicious, which it acquired in 2005.
