I haven't seen you around as Deadpool, is why.
See, a big part of the reason it's difficult to keep track of people is that half of them are always changing their profile name. I really don't know why they do that. It's like when women constantly move furniture around. I really don't understand that either.
Granted, I myself have altered my profile name a couple or three times in 4 years, but I always kept the Chuck part in there. So many that do change though go hog wild and start using something completely different, so it becomes real hard to keep up with the changes.
It would just be like, in real life, if every month most of the people you knew started using a different name. You just get to know a person as "Bob", and then suddenly he's "Trent"......Get's confusing.
