Aardvark - Ask a question by email/IM/web and the Aardvark community will answer you.
Glitch - The game. Shh.
Postful - Postal service. Great for people who don't have email addresses, e.g. I can email my grandma via Postful, and Postful prints it out and mails it to her, including photos/attachments.
