"Also, flickr has a 200 photo limit on free accounts that makes project 365 impossible unless you upgrade, and even less so if you use flickr for something else."

Incorrect.

From http://www.flickr.com/help/limits/

"When you have a free Flickr account, you can upload 2 videos and 300MB worth of photos each calendar month....Your upload limits are reset to zero at midnight in Pacific Time Zone (Flickr headquarters time) on the first of each calendar month."
