I've currently got 184 blogs on my
bloglines reader. I would DIE without bloglines, which allows me to check all the blogs that interest me from a single website. Bloglines lets me know when there's a new post on somone's blog, thus saving me from opening blogs one by one and hoping for the best. Even if someone only posts occasionally, that's fine with me once I'm set up to get their feed.
Blogs are huge in my daily reading, and they run the gamut from friends' blogs about their personal thoughts and doings, to blogs about news and matters of personal interest (running, triathlon, writing, animals, etc). I've made some wonderful friends and contacts by exchanging blog comments, and I've gotten tips on interesting books, products and places to go. I've gotten writing and fitness advice, recipes, and new ideas. And I've seen lots of great photos.
I'm currently writing two fiction blogs of my own, one of which I update nightly. My vacation blog only gets updated when I'm actually on vacation. And my two personal blogs are for whatever random ramblings I think of at the time. I try to update my main blog (tri-bunny) at least once a week, though.
I get moderate traffic to all my blogs, although I wouldn't mind more. But I don't blog with attracting readers as my first goal. I do it because I like to write and share. Is there any better reason?
