Not that this matters but I’ve been on Twitter 7 years and never have had to supply my phone number.
Actually; it DOES matter...it is the reason I am NOT watching on FrankSpeech, and I am damn sure there are many others like me.
I remember when curiosity got me way back in the very beginning of Twitter when the church I was going to at the time was trying to be all trendy and innovative with social media, and I remember trying to sign up and it needed your mobile phone #. I said F-that and never looked back.
