WordPress Sample Post
If you happen to create/tweak/change a wordoress theme before , one of the major problem is you need to create different kind of post format combination, so that you can confirm yor theme doesn’t break under any post format. I have see before some of the theme looks extremely nice, but when you have a order list after a quote , the whole layout might just broke.
Wpcandy actually release a sample post collection in xml format which allow you to import through the wordpress build in import feature, these sample post collection consist of different format example like blockquotes, lists, and floating images, you can just test your theme with all these combination and make sure the theme working properly.
This is really a nice collection that helping developer/designer when working on the theme.
