I spotted this article on Techmeme from Om Malik suggesting that PicApp could provide free stock photos from the likes of Getty. Possibly useful for some niche blogs if you want to avoid legal problems.

When Blogcatalog was relaunched, the links from the directory were nofollow.
In my initial review I suggested that it would be a popular decision to remove the nofollow from the links, and also use a different method of tracking clicks – Blogcatalog have to track clicks because it is part of their blog rating system, and might also help with advertising sales for premium positioning.
Some things are very easy to install on a blog.
coComment is certainly one of them
