Instead of having a stream of the latest picasa pictures, let me choose an album to show up, or have a gallery view of my albums. I doubt everyone who comes to my landing page wants to be greeted with a picture of me shirtless in Belize.
I own the domain for my own name. I'd love to use skrawlr as a way to get people more connected with me. It's much cleaner to direct people to example.com than it is to send them to example.skrawlr.com
At the moment, we do not support custom domains, but we will be adding support for them in the future. In the meantime until we have this implemented, we will be allowing our users to use a masked forwarding/iframe-type service (such as those offered free by dot.tk, dynadot, and many other registrars) to point your domain to your skrawlr page.
