Basically, all a theme does is control the look of your blog, and (sometimes) makes it easy to add certain features, like ads, forms, lists, etc. So just pick a theme that looks good to you and lets you add the elements you want to your blog and be done with it… no need to make a big deal about it. Telling your readers how to set up a theme for a specific task is informative and useful. Telling them how cool your new theme is, is a waste of bandwidth.
