Approaching our second anniversary, it’s interesting to look back at the growth of IT Conversations. Here are two charts of the past year’s activity. The first shows the number of registered users, now approaching 10,000. 15%-20% of downloads initiated through the web site are by registered, logged-in users. There’s no way to determine how many of the downloads initiated via RSS (now the vast majority of the traffic) are by registered users.

The next chart shows the traffic of audio file distribution, combining that delivered by Limelight Networks (the majority) and our own servers (for ShoutCast streaming only). On our peak day, we hit roughly 220GB, the equivalent of nearly 7TB per month.

Regarding the dip during December-February, my guess is that it’s due to the lull in the conference season. [More stats here]
