Personally, I try and limit opening swapnote to once a week now. I hate the fact that it is in all my records as a top 3 played game so now I'm trying not to skewer that percentage so high and open it everytime I see a blue dot.
Also, to me, the majority of swapnote messages are things that could be posted on this forum and I'd rather talk about those subjects or comments here than trying to scribble out some readible words in a limited space. Back when Swapnote was at it's height and lot's of people were passing notes back and forth, there were many times I thought to myself, why don't people post that on these forums instead? I'd rather see this community stay strong than participate in limited Swapnote discussions.
That said, there are definitely a few things that work better on Swapnote than here such as some jokes and quizzes. I had one idea I still might carry out but lately I just try to use the system to play games than spend time to make comments or watch videos.
