Bob Cringely finds weblogs inexplicable and wants a way to search them.
Weblogs let amateurs pontificate and think in public, just like Bob does for money. It is fun, after all. It would be nice to get paid too.
Unlike mailing lists, chatrooms and Usenet, they don't get polluted by spam and trolls because they are controlled by individuals.
You don't need to read them all, you just need to find a few you like and read those - the searching is done by individual selection.
And Google does index them very well - the individually made links in weblogs are a key part of what Google consolidates into a consensus about what is worth reading. If the weblogs say something interesting on a topic, Google will find it.
Once you find a weblog you like, use this tool to find others.
Look for followups here
The way to read them is an RSS aggregator like NetNewsWire.
