Double post I know, but I decided to look at how different sites (my blog, different wikis) look like when viewed with a smartphone.
... Of course, being the sort of person I am, I decided to go one step further. Not content with busting out a smartphone and hitting up its browser (and more influenced by the fact that a smartphone was quite simply out of reach at the time), I just used my PC's browser to view my blog as if it were an Android, and Hatena (thinking I was an Android) sent me the mobile version of my blog... but dang, it was pretty nondescript. Same with some of the wikis I visited - there was some pretty stone-age looking stuff out there. For the record, these forums don't have a unique mobile version, but I'm guessing it's already mobile-friendly.
I wrote about it on my blog, so anyone wanting to do the same can take a look. The technical details might be a little too long for this thread.
