I’ve been on Twitter since 2009. Hate the trolls, but the system is honestly pretty smooth.
GAB and Parler have good and bad elements. Trolls are not a problem yet, but both systems seem a little bloated. Parler seems more graphic. Not sure how well it will handle rapid growth that probably is coming.
Gab never seemed to run right on my phone. Also, there’s only so much time, and back then I actually paid attention to Facebook. Twitter can be a cesspool depending on the crowd. Twitter needs real competition.
