Tapatalk has done one thing that keeps me on with them: they push notifications continuously regardless of visiting the site. I actually like this compared to a single notification and then nothing until I visit the thread again. If a thread blows up or becomes very active, I get a notification for each reply. I very much like that. No other app does that currently, while at the same time being free.
But this one pushes me over the edge. They actually replied to Morganna's thread, but ambiguously, then locked it.
