I often read the forum from my smartphone, and unfortunately it's not easy for me to write long detailed posts on my phone. So when I want to react to a post or a topic interesting me and I'm on my phone or if I have no time to write all I want to say, I briefly reply to it and I complete my post later when I have more time or when I'm on my computer.
If that's a problem, what you could instead do is to save the topics or posts that you are ineterested in replying to and then simply do it when you have more time or when you are at the computer. At least That's what I sometimes do as I also like to browse the forum on my mobile phone while in bed or on the couch etc.
Anyway, not the smart move at all...
