Hi Rodney,
These are good recommendations, and we've been thinking about having online code and diff browsing almost from the beginning.
However, we've historically been more interested in generating software metrics than in creating an online code browser -- we assume everyone already has one of those. Therefore we haven't prioritized it. But as time allows, it is something we are thinking about.
Even the revision number isn't always possible to display. I know it seems nuts, but the Ohloh back end data gathering system was not originally built to preserve the Subversion revision numbers for online display, so we don't always have them. However, in many cases we do have the data, so we can look at adding that in the cases where we do have them.
Thanks,
Robin
