One element the new
/about page lacks is a place to highlight specific sister sites that user might be interested in. For example, someone looking at Stack Overflow's
/about to see if they should ask a database architecture question may not know that dba.stackexchange.com exists.
I think the logical place for this would be the bottom of the About page, something like this:
This could be populated automatically (using the broad categories of Technology, Culture, Recreation, etc.), but I think it would be better to have the communities/mods select related sites to highlight by listing their URLs, similar to the way sites onebox in chat.
For sanity's sake I would limit this to 4 or 5 sites.
This is really more relevant to the technology (SO/SF/SU/Security/DBA/Apple/AskUbuntu/etc.) sites, but the list could simply be left blank for sites that aren't "strongly related" to others on the network.
