I have a better question. How many of these people are actually posting? It feels a little pointless to follow a bunch of people who have no public posts.

I've gone through all the links in this thread (at the time of writing) and included only those where I can see posts (i.e more than just uploading a profile photo). I've simply copy/pasted the links from the original submitters into this post. Hope it's useful. (edit: I also put them all in a spreadsheet which anyone can edit http://bit.ly/nBqc8e)
