I've never been a big fan of people who post blogs that just point to another blog posting, essentially reiterating the original point. I've always thought the motivations behind these can too often be lame attempts at name recognition, increase hit-counters (ad-counters), or just the "I want to be part of something bigger" that I feel permeates the blogosphere.
I do feel there is some merit in linking to a blog if you're refuting someone else's blog entry, or referring to them to enforce a point of view, but all too often I feel these "blog redirects" are just an attempt to increase hits, with little to no additional substance involved.
This is one of the reasons I haven't put ad-banners on my page. I decided to blog as an outlet, not as a money maker or for industry recognition - hell, I don't even use my real name. The anonymity is something I enjoy, not because I can say stupid shit without people being able to hold it against me (those of you who know me socially know this is the last thing I worry about when my lips move). I write these little tidbits so that I can share some thoughts that otherwise would need to be sensored for various reasons, or I just believe I have something valuable to contribute.
I will admit to having a bit of a soft-spot for humour though (shameless redirect to something that had me laughing http://www.vitalsecurity.org/2007/03/browser-condom-opinion-split.html). I think sharing someone else's great (and especially funny) idea is good, and it gives credit to the person who came up with the original content. I am NOT going to provide links to the type of content I'm talking about - that would be somewhat hypocritical - but if you're reading this site (which gets very little traffic) then you read enough blog entries to know the type I mean.
My point is this:
If you blog, and you are talking about someone else's article, please make sure you have something MEANINGFUL to add, don't just rehash (sometime badly) what the original author wrote, then link to it. Alternatively, if you really liked an article, a nice suscinct intro to a "good article about..." is usually enough - don't try to make the idea yours.
