I picked up a good tip somewhere on the interwebs about using domain names for branding and as a way to simplify your own life, via URL redirects. Apache makes this easy, you simply edit your .htaccess file and add a line like this:
Redirect /flickr http://www.flickr.com/photos/wheat
Assuming the .htaccess file is at the top level of your website, you can now use something like wheatdesign.com/flickr to forward visitors to your profile page on the social networking site in question. This is handy, especially if you’re pimping something and want to keep your own URL front and center (on, say, print media). It also means you never have to wonder what URL scheme the site in question uses for profile pages.
I’ve set up several for wheatdesign.com and intend to set up the same for my other domains, as I can never decide which one should have precidence.
A note on style, you’ll want to resist the temptation to put trailing slashes on either the shortcut or the place where it redirects, as doing so will often confuse either Apache, or the service in question, or both.
