Shetoldme and Snipsly are similar to Xomba. You need to submit a summary of your post as bookmark.
RedGage is simpler where you create a Title and just link your blog address to it. YouSayToo is even better as every post you make will automatically be posted in YouSayToo (downside, only provide link back to your blog's main page).
Plus point. All of the above offer Revenue sharing. The sharing percentage differs. All except RedGage, revenue is through Adsense. The more clicks the more money. RedGage pays based on pageviews of content submitted. The more views the more money.
After signing up with these, it's time to submit the links. Tedious work but I think it's worth every minute of it when you see traffic coming and money trickling in.
