Hmmm, if I were to guess, I'd say I've spent about 1 -2 hours MAX on Twitter in the last 9 years. I could never really make sense of it, never saw how it added value for me. So, delete it? Sure, why not, when I get a chance (or if I remember)...I actually can't even think of the last time I was on there, but next time I get on, I'll delete :)
