Ask HN: review my startup, WatchdogDaemon
http://watchdogdaemon.com
Honestly I'm not sure I will send a quarterly newsletter, I just wanted to cover myself incase I did in the future for people that pre-registered but never signed up after an invite.
In your case how big of a barrier to signup is that?
I like idea for a REST API graphic, I'm just not quite sure how it should look.

Its currently in private beta, I'm going to be sending out a fresh round of invites, if you signup and mention HN I will move you up the list.
