Wow, what a great find! Bookmarked!
http://www.reddit.com/r/MapPorn/ (should be 100% safe for work - it's just maps that are, well, gorgeous).
There are some good 'surbreddits' on there for creatives...
Some for world building, character creation, conlang, and so on. It's worth exploring.
'MapPorn' Interesting name, good find nontheless.

Yeah, at first when I noticed several ____Porn subreddits in the list, I didn't know what to think - but in many cases (e.g., /r/humanporn I think is one), it's just meaning 'awesome', nor pornographic.
