MacroDroid propably does not have 5 times more downloads then Tasker. The numbers on the play store are very approximate. I think until recently MacroDroid had a million + as well as Tasker and then it jumped to 5 million +. Also as MacroDroid is free, there's plenty of people that just try it and left it immidiately.I think the biggest reason there's not much forum activity is that it's just so easy to use. It has 5 times the number of downloads Tasker does (maybe that's the count after Joao took over?), but...basically not many people need help with it. That's my guess. It's sure as heck not representative of the user base.
