Add more Adapters

[zmoshansky]

Definitely Useful (IMHO)

• Logger
• Email
• Google Analytics
• Push notifications (iOS, Android, other)
• SMS (ex. Twilio)

Interesting to explore

• Phoenix Channels (This may be too application specific)
• App monitors (Nagios, Airbrake, etc)
• Telegraph (Because why not)

As for everything here, open to PR's feedback, etc.
