The wonky part for me is that there are three separate windows, where as in Photoshop it's all one window with toolboxes that you can drag around. So if you minimize The GIMP, you have to actually minimize all three windows. This is a hassle. Plus, it's sometimes hard to make the windows stack in the right order.
Specifically, there's a post about the history of the McRib, but since people are allowed to write anything they like as their tag, it's listed as #wheresthebeef. There are no other posts in #wheresthebeef, nor are there likely to ever be. So even though this is a cool story, it doesn't let me find more like it, because of the lack of restrictions on tags. It could be under #food or #fastfood or even #mcdonalds, but as a once off tag it has less utility. So perhaps if there was an algorithm to suggest tags based on the content of the article it might help.
One criticism I have that has stopped me getting into this site more than my other social news haunts, is that since hashtags can be anything, a cool article doesn't allow me to find other cool articles via its hashtag as often, because it might be something too specific. I'm not sure if that makes sense, or how to address it really, but perhaps a suggested hashtag feature?
