I deactivated my personal Twitter account two or three weeks ago because I did not like the direction the company seems to be moving in. I suppose I didn't want to become angry with a company whose service I have often found to be rewarding and useful, and wished to part on amicable terms.
I enjoyed Twitter more than Facebook or Google+, whose accounts I've kept. But as a rule do not participate much in those networks. For now, besides WordPress, GNU Social is where I put stuff. I'm thinking to set up either a personal instance of GNU Social, or a Friendica or Red instance, on my new Raspberry Pi.
