To prevent the problem of spam linking, an Authority points are calculated based on the number of blogs that links to you. Even if there are 200 links pointing to you from a particular blog, the Authority point is still counted as one. Read about Technorati Authority here.

2. Boost your Google Page Rank via blog linking. Part of the formula used by Google to determine the Page Rank(PR) of a blog involves calculating the number links pointing to that blog.
Although there's always the issue of link spamming(also called spamdexing) that Google is trying to overcome, I doubt it should be of any concern to you unless you're spamdexing as well. My only advise is to build more credibility for your blog and the links will eventually come from your readers and fans.

3. Discovering that other blogs are linking to your blog is a great confidence booster. In some ways, links from other blogs are seen as the ultimate recognition for a well written post or article.

4. In the virtual world of blogging where physical contact is not possible, handshakes and hugs between new found blog friends are made via blog linking.

5. Sharing your readers with blogs that you link to. Let your readers know that you are not stingy when it comes to knowledge and information sharing. If you lose your readers by doing so, it comes to show that there is much to improve on your blog. Blame not your readers for jumping boat(blog), but yourself for not doing enough to captivate them.
