I hate blog posts that sound like they might be educational, but end up being nothing more than attempts to get conversation going. That strategy is welcome in a forum, I do it myself all the time. But blogs should be an offering of knowledge, opinion, or just interesting thoughts, not a plea for readers to supply same.

Here's an example: Do You Really Need Photoshop?

It has a great title, and got linked from another blog (the point, I expect). But the title question...

The cliche of blogs is that they recycle links to other blogs, so who am I to argue?

Here's a couple of interesting photo-related links:
87 Great Photography Blogs and Feeds (your blog here could be one of these one day)
Broken Camera (or is it better than it was?)

That's enough unoriginal content for now.
