I haven't had time to implement it, I wanted to get the signup working quickly.
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 think you could have one sort of flowchart at the top of the graphic, using arrows to indicate how my servers and devices can be pushing out calls to your service etc.
I don't know the ins/outs of what you're doing, but think:
my server -> your awesome service -> oooh charts
Then underneath this main simple illustration, perhaps in grayscale, you could have an example of the "old" way to do something like this (and point out why it sucks).
I have created http://watchdogdaemon.com by myself. I need to be able to monitor client applications at multiple hosting companies that are behind firewalls.
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.
