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.
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.
