I spent some time this afternoon poking around in the database that runs UCalgaryBlogs.ca to see if I could get a better sense of how it's growing. Turns out, it's growing MUCH faster than I thought it was (and I thought it was growing pretty darned fast).
It's still pretty small scale, compared with giants like WordPress.com and Edublogs.org, but the growth looks pretty much exponential. I'm glad we've got lots of room to scale this puppy. And that campus IT isn't upset with growing demands on database resources.
