Can I ask how you're scraping and aggregating the news? I tried long ago to make the same thing for me but ended with horrible results :/ (yahoo pipe was so great for it)
For the social media, I guess you're using API but the websites (with no RSS)?
As for suggesting more sources, there are sooo many. BitcoinMagazine.com bitcoinist.com...
You can even think to play with google alerts
The news area could need more newspaper sources, not only CoinTelegraph

(I don't know, btctimes and others, although I know that if they're too many you'll end up with duplications)
Easy to deal with duplications if
Regex is used
