Exited to see these new SDKs for the Echo, using it daily it definitely gives you a feeling for the vast potential of the platform given 3rd party contribution. Using AWS Lambda also makes development of Echo apps makes it extremely easy, it took me only about an hour to get a working prototype of a simple app working.

I'm looking forward to attending the Boston amazon developer day this weekend to really dig deep into all the sdks and get some questions answered from the team.
