Nowadays, there are so many social bookmarking sites, e.g.Del.icio.us, Digg, Facebook, Fark, Mister-Wong, Newsvine, Reddit, Technorati, Slashdot, StumbleUpon and etc…
What do you to do if you want readers to promote your content? Encourage your visitors to submit their favorite stories directly to Digg? Not everyone uses Digg. You have to decide on which bookmarking site, if any, to dedicate your precious screen real-estate. It’s a hard choice. If you choose poorly your reader won’t vote—it’s not a single click coupled and out-of-sight means out-of-mind—and your content losses its chance to make it big. You have to choose your horse wisely.
On the other hand, if you take the bird-shot approach, it overloads your reader with branded badge after branded badge. It turns your page into the village bicycle. Not pretty. Nobody seems to have solved the problem yet.
If you could detect which social bookmarking sites your reader uses, on a per-reader basis, you could display only the badges they care about. SocialHistory.js enables you to detect which social bookmarking sites your visitors use. SocialHistory.js has a big list of the most popular social bookmarking sites which it checks against.
