It's been a while hasn't it? The web 2.0 market appears to be clustering around common services in a big way so finding new stuff has been fun. Yet there's tools and services which can provide useful for gamers so don't despair even if we're on the slow road to recovery.
Free systems - If you like mecha, take a look at Gunwave. Those of you who fancy Harry Potter (slashfic ahoy!) can consider Broomstix (a light RPG). RPG Objects are offering the Two Worlds RPG for free. If you prefer your action a bit more Hong Kong/Korean-style give Wushu a shot.. Those of you fancying a bit more collaborative-paced story may want to try Archipelago II.
Organisation - Shout'em is a service that lets you make your own microblogging social network similar to Twitter. It's also mobile compatible for those who can't stay in front of a computer that long. Some elegant privacy and integration options as well. Use this to organise gaming groups or fan clubs.
Printables - Printable Paper offers you multiple styles of paper including storyboards and perspective grids as well as the more typical hex and square grids. Love for calligraphy, musical notation and printable games makes this even more impressive.
Talking - If you're looking for a (currently free) voice-chat client, try Voxli. It handles up to 200 folks at once (which deals nicely with online flash mob style gaming and interview chats) and has no limit on the number of rooms. It also stays within the browser. Enough for anyone, surely?
Woolgathering - Want to throw some ideas at a wall? Asking for feedback? Give Wallwisher a try as this virtual wall lets people put virtual notes on with a 160 character limit on. Being able to embed images, links and videos are options as is setting up a private wall or two. And it integrates with your Google login.
