tl;dr

I maintain various other bits and bobs around the web.

• I have a LinkedIn account for serious work type stuff
  
• My main photodump on the web is my flickr account
• I  write stuff on my Twitter account
• I like to keep my bookmarks over at del.icio.us
• My music tastes are tracked in my last.fm account
• Even my Xbox 360 has a blog

I have accounts on all the major games consoles:

• DoctorGlyndwr on Xbox Live (not RichardGaywood any more)
  
• DrGlyndwr on PSN
• Some collection of numbers on the Wii which I’ve fogotten right now!

There are also a few web forums and suchlike I am sometimes active in:

• My friends and I share a social networking site, Eggwan.com, of our own devising
• Be Excellent To Each Other is a random forum, somewhat based on computer gaming
• I used to play a lot of Unreal Tournament with the great guys at Titan Onslaught
• I have a long term soft spot for Usenet, I was a longstanding regular in alt.digitiser and I occasionally post in uk.games.video.misc.
