With all the buzz around recent Google Blogsearch relaunch, I thought that would a good idea to look at most popular blog meme trackers available online.

Blog meme trackers (or memetrackers) monitor what is most actively passed from blog to blog (“If the thing is actively passed around, that must be hot“). In a word, meme tracking is all about identifying, collecting and arranging most talked-about news in blogosphere.

The three available (and similar) meme trackers that could really compete with each other include:
