I'm looking into #Diaspora protocol stuff for the !hackfest but I can't seem to do a non-hacky method of looking up the profile's feeds etc. based on their URL. No metadata is embedded in GET or HEAD data from, say, https://joindiaspora.com/u/maltman23 and a #WebFinger lookup on their server doesn't reveal data unless I use an acct: URI (acct:maltman23@joindiaspora.com). I could of course construct that myself (take nickname, take hostname part of URL and glue together) but I'd prefer not to.
