Should I try to post on weekends?

I tend not to post on weekends because (1) I’m often traveling to Seoul on weekends, which makes blogging hard and (2) I feel like I need time to build up post ideas so I have something to do during the week. But recently, I’ve been wondering if posting on the weekend would increase the retention rate of new readers, so they won’t finding themselves reading for a few days and then wondering where I went come Saturday.

I really have no idea. I’m unusual in that I do almost all my blog reading with the help of Google Reader, so I’d never do that with a blog, but other people might. Comments on this post will almost certainly be unrepresentative of my readership as a whole, but give me your input anyways.
