I didn't use bloglines so far, but it seems interesting: keep all your preferred blogs on server side and access them from anywhere (home, office, restaurant,.. ) and anyhow (laptop, PC, PDA, mobile phone...). Add and remove of blogs is easy, you can even select your blogs from a large list.
Web is becoming more and more dynamic as everybody is an information source (compared to few years ago where some content publisher offered content, and private information publishing was limited to web pages). Blogs have changed this completely in only 2 years. Now you need services like bloglines to manage this new kind of information. Searching is just too much static. The dynamic web is present and we are living this great adventure :D
