Good points.
Generally, if there are a lot of posts to get through and I don’t have the time, patience or energy to work through the list, I tend to ignore those that are least descriptive. I restrict myself to working only with those posts where the poster has taken the time to draft an informative subject line that leads nicely into their post.
The “mouse over” also really helps cut down on non-productive browsing too!
