Free advice if you have a blog -- don't bother with descriptions. Descriptions only show up in aggregators like SharpReader, and most people would rather see the full article in the aggregator anyway, which happens automatically if you don't include a description.

For that matter, you don't even need to include a title; the start of the article will automatically be used as a title in that case. People who generally blog dozens of entries every day don't bother with titles; I figure with just one or two a day, I can bother to come up with a useful title for each entry.
