Ohloh is a nice social network completely focused on open source software. Basically, it can extract all sort of information directly through source control extraction and analysis.
Based on the Ohloh estimates, developing the Lokad products should have cost us $1,766,626 assuming $55,000 per year per developer. To be honest, we did spend that much. :-) We are obviously a bit more productive that what Ohloh is expecting.
Do not hesitate to grant Lokad a few Ohloh stacks. We need your support to expand the coverage of our open-source contributions.
