We have reached the point of diminishing returns on links to other blogs thanks to all of the Link Whores out there.
Providing links to 30 or 50 or 100 other bloggers on your site makes every single link meaningless. It doesn't tell us anything about who you think is actually worth reading, all it does is show that you are a link whore.
I mean, who are we kidding. If you have links to more than a dozen other blogs on your site, we KNOW you don't read them everyday unless you have WAY to much free time on your hands.
Blogging, by its very nature, is a narcissistic enterprise. But we've reached the point where people THINK that the more blogs link to their own blog, the more important they are.
