Like everybody in search we are having to get more involved in Social Bookmarking than we used to be.
Like most people in search, normally we don't have a lot of time for social bookmarking. It's a pretty busy year.
On this weblog, we've implemented Denis de Bernardy Bookmark Me plugin which gives direct access to 25 services (del.icio.us, Digg, Furl, Reddit, Ask, BlinkList, blogmarks, Blogg-Buzz, Google, Ma.gnolia, muti, Netscape, ppnow, Rojo, Shadows, Simpy, Socializer, Spurl, StumbleUpon, Tailrank, Technorati, Windows Live, Wists, Yahoo!).
We've selected del.icio.us, Digg, Ma.gnolia, StumbleUpon and Technorati for now. I would really hate to see more than five icons at the bottom of my posts. Even that's a bit of a stretch. The PR drain would be terrible but Denis de Bernardy very sensibly allows us to automatically put no-follow tags on all bookmarking services with a single checkbox.
