Last night at our local .NET User Group meeting I was catching up on my RSS feeds as Eric Maino was doing his nUnit presentation (no offense to Eric but this was stuff I already knew). I stumbled across Scoble's post about writing descriptive headlines to help get your posts read. I totally agree. I've been so busy that I had 500+ items in RSS Bandit to read. Obviously I couldn't read them all so the headline of the post was a key factor in whether I read it or not.
But another thing that bugged me about some posts is the amount of graphics included. I was working offline with no internet access. I realize that a picture is worth a thousand words, but some posts were simply copy/paste from an HTML page -- which included all of the IMG tags. Sure, it made your post look "real pretty" for most people but those of us doing offline reading were stuck with a bunch of red-x boxes.
I'm not saying images have no place in blog posts, I just think they shouldn't be overused and consideration should be give to those who may be "offline".
NOTE: Updated 9/17 to include the link to Scoble's original post. Sorry.
