It makes for an interesting tag cloud of which composers the choir sings
most as well as the venues that they sing at. I'm pretty sure it also
drives search queries to the site as well. Since I moved to this way of
managing the site we certainly get more hits via search engines due to
people searching for composers.

Oh, for what it's worth, I had to comment out the backup stage in the
rails installer for another one of my blogs as it used all the memory up
on my virtual server :). That blog has a LOT of content and the rails
backup seems to grab all the data from the database into memory and then
dump it to a yaml file. Given I do a manual sql backup anyway before
every upgrade losing the backup stage isn't a major issue.

Ah ha. I see! It must make the tag management more difficult though,
especially deleting tags from articles!

Great, thank you.

Good to know...
