One of the things I enjoy about blogging is getting a chance to read comments that other people post in regard to my posts. This can actually be quite educational and can help improve the blog. It also gives you the opportunity to establish an on-line friendship with people who have the same interest as you.
There are actually sites where people can register to find people who have similar interests; where they can establish new friendships and see if they can find old friends as well. For instance, people may want to join 3gb community www.3gb.biz for such purposes.
