Yes stumbleupon.com and digg.com is most using social bookmrking sites, but i use always twiteer, as a blogger I’m interested in building traffic to my web properties. Twitter has been an increasing source of this traffic over the past year or so. While it isn’t my primary reason for being on Twitter it certainly is nice to be able to post a link to a post that I’ve written or an online project that I’m launching and to see people coming directly from Twitter to that page.
