I posted a similar topic a couple of months ago and had very few responses. Now that this forum is a little more active I though I'd try it again. These are the ones I follow:

1. Megatokyo , of course

2. Sluggy Freelance , also very popular

3. Kagerou , I like this one a lot

4. Under Power , has a lot of violence and some nudity though, so rated NC-17 for you kids...

5. 8-Bit Theater , very funny

6. Sinfest , funny, cute

I also recently found this which is just plain odd.... Anyway, post your own links.
