It seemed like a good idea, I took some screenshots while setting it up and was going to write a lengthy post about it today.
I was honestly quite excited, as I find various kinds of meme trackers extremely useful.

WTC actually highlighted Techmeme in their title – I actually much prefer to use custom Megite memes such as this one on SEO and I get it updated all the time on a Google Toolbar button.

BlogRovr might be a good idea, but is limited to only 100 sites.

Add a Zero

The idea of meme trackers is to be able to handle more information than you could otherwise cope with in a Feed Reader. A limit of 100 is absolutely useless for any serious use.

Increase that number to 1000 and I might be interested in taking a deeper look at it and maybe giving a recommendation.

If you can’t handle the data, invest in bigger servers, or limit your beta to fewer people.
