Just a further data point. As of the end of last month we had edits from 324'152 unique UIDs, not quite 30% of all accounts (some of the changesets are likely to be empty, but the number is still quite a bit larger than the often quoted 200'000).
While there is clearly room for improvement in converting account creators to contributors, I believe the number is actually quite good. It would be interesting to compare our numbers with data from other commercial operations, say FB, however what I have seen from their SEC filings is that they do not show numbers for actual active users (vs. just logging on).
