@breefield: The compete metrics are way low for us. Like, less than a third of what we actually have. (Unless you’re in the top 20–30K visited websites, compete and alexa numbers are usually meaningless). Alexa and even compete really are only meaningful for showing general trends and persuading naïve investors.
A much better picture of us is Quantcast, since we’ve actually started providing data to them last week.
As far as users go, we’re nearing 8K, with about 500 very active users in a given week. We have over 15K discussions, over 125K responses, with around 1K responses per day now. We’ve seen over 200% growth in the last few months, and we serve up about a request per second.
