I recently "discovered" the Optional Excerpt feature in WordPress, which is sad considering that it's been in plain view the entire time. From here on out, readers of my RSS feed will get a summary of each post instead of the first N characters. This should help make each post's intent more understandable. The only problem is whether or not I'll remember to create an excerpt with each post. I've clearly got to train myself to take this extra step before posting.
One other interesting feature that I recently learned about is the "post slug" field. This allows the author to specify what text to use when creating the permanent link for the post. How awesome is that? No more awkward contractions in the permalink URL's!
