Introspection for a blog is a good thing, and will always be part of any good blog. Old media doesn't do as much of that, they don't have to wonder what is their core purpose -- they know that their job is to deliver advertising. The good ones try to reach that goal by being interesting, etc., but that's not why they exist.
(That said, it's clear that the big papers will soon be much like sports teams, owned by people with oversized egos. The two best examples are David Geffen trying to buy the LA Times and now Rupert trying to buy the Wall St. Journal. Warren Buffett and I spotted this trend at the same time!)
A blog is different. Well, it is for all those people who aren't so nefarious as to get into pay-per-post, etc.
I've seen two great bits of introblogtion recently from two of the best.
The first one is from A VC:
I know one thing for sure. This blog has to have a personal feel or its just another windbag pontificating about technology and we already have enough of that on the web.
The other one is local to me, Brad Feld. In that one, he makes a connection between what he read about Global Warming and what a reader sent to him complaining about the blog.
Both are good, but Brad's, I think, does what good blogs do best, which is make connections between things that may not seem to be connected.
Now, you may be asking, why am I linking to two different VCs in a blog that is designed to talk about how to avoid VC? That's a good question!
