i can suggest you reddit.com/r/GirlsGoneBitcoin
I will never use reddit.
Ever.
I hate that site with the fury of a thousand suns.
I actually sent a blanket e-mail to one my comp sci junior level classes with a picture of shit with the word "Reddit" written above it.
Too much reddit and too much apple use was observed in that comp sci department, someone had to make a stand.
