I'm glad my blog entries will show up in search results. Some of the questions that I answer on my blog might apply to other users, but they'll never see them if those blog entries don't show up in the search results. In the meantime, I'll keep adding entries.
How many people do you think use their blogs here on moodle.org? I've seen some very active discussions on the use of Moodle blogs in the forums, but not much actual use of them here.
