Hacker News Bot for Facebook Messenger

I'm building a Facebook Messenger Bot for Hacker News, a site we all love to get tech news!

The bot can send you personalized news:
Send you daily updates with link to BOTH the stories && the invaluable HN comments!
Search for keyword across Hacker News stories (just send the keyword in a message)
Subscribe you to your interested keyword (for daily updates)
Get you Top and Best news any time (from my menu)
View what keywords are trending across bot users

Of course, you can always unsubscribe from these updates!
