Just got rid of my old custom theme here. It was slow, and the design was honestly starting to piss me off. I just reverted to WP’s default twenty-twelve theme.
Now. I imagine there will be some problems with layout etc.. I can already tell comments look a bit wonky; but at least I don’t have to wait 5+ seconds for my custom fonts to load anymore ;-). I’ll give this site the update it deserves at some point in the hopefully not-so-distant future.
