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)
I've seen in the past a crypto news aggregator with many sources. I don't know if they were using Regex or not (heck, I don't even remember which aggregator it was), but I remember I've seen the same news in many places with somewhat different title and wording. I don't know how good can Regex handle this.
