Earlier today I helped someone set up a mobile version of their website and that finally spurred me to launch a mobile site for this blog. (WordPress makes this really easy, in case you were wondering.)
Second Update: Someone showed me a better way to do it, so I've killed the mobile domain. Your mobile device should now be auto detected from the main URL.
To be more accurate, I've had a mobile theme since late August (which you could access through a theme switcher widget). What I added today was a specific domain for the mobile theme. I'm currently using a theme called Carrington Mobile. I've tried it on a number of different screen sizes and I like it. (But if you know of one that you like better, let me know.)
While I'm on the topic of mobile themes, I have a question for you. Four percent of my visitors are running Android, but not very many visitors are using the mobile theme. (I'm tracking the traffic.) I'd really like to find out why the mobile theme wasn't used much; maybe it's something I could change. Answered: My old way of switching to a mobile theme was clunky. I thought it worked okay, but apparently no one else knew it was there.
Any feed back would be appreciated.
Update: Thanks to early feedback, I've enabled browser detection. If you are visiting from a mobile device you'll be kicked over to the mobile theme. Don't worry, you can switch back. I'd prefer not to do browser detection, but if this works for people I'm fine with it.
