What WordPress theme is that?
Ever seen a WordPress blog and loved the theme, but there is no link at the bottom of a site to find out what it is? Here is a site that will tell you simply by putting in the domain. It will also tell you some of the plugins used on a site.
Is your blog RSS feed working?
This site checks if your RSS feed is working and a few other things too
What font is a site using?
If you use Google chrome (I am sure similar exists for other browsers) you can add the WhatFont extension to the browser. It allows you find out the font, colour and size of any font you see (that isn’t an image)
