I use twitter, mainly for news. Since I've gotten on Reddit though, my twitter use has dropped significantly.
Who uses the twitter?
I've had an account for a while, but didn't tweet often. Since deleting facebook I've been using it a lot more. I've found it to be a great resource for getting better deals without having to actually talk to a person. I recently tweeted at Cincinnati Bell that our bill was too high and speeds were too slow compared to what I could get from Spectrum. With just two tweets, I lowered our bill by $25/month and increased our speeds from 200Mbps to 500Mbps. Not bad.
Also, following our dear leader is good for a laugh.
