I like it! I think your format is informative and clear, concise enough that people don't get bored but gives enough information for people to decide if they're interested. Following a blog like this, I'd be happy with daily reviews, provided they were tagged in a way that I wouldn't have to scroll through five pages to find that comic I liked the sound of last week.
I think you should have a good mix of reviews for more popular webcomics and smaller ones - while all webcomics need promotion, and there are some popular ones you'll really want to shout about, I think there are a lot of webcomics that slip through the cracks without people scouring for them and telling their friends, which with a blog like this you can do!
That being said, I'm never above a bit of shameless self promotion, so if you'd be interested in reviewing my new webcomic I'd really appreciate it. I'd also like to plug Witchy, one of my absolute favourites, which you and your followers need to know about.
