A new signature campaign has popped up: The Merkle - it does have a couple of red flags, though: the campaign thread is self-moderated, and the campaign manager, themerkle, refuses to use escrow (and the pay per post is quite low to boot).

This is what the Simple Table entry should look like:
PNYC | | | The Merkle | | | post/weekly | | | 0.0004 | | | 0.0004 | | | 0.0004 | | | x | | | x | | | x | | | x | | | 20/w | | | 100/w | | | N | | |
