Do you want to feel more unique by being able to customize your avatar to a greater degree?
I like to be fancy, so, while it doesn't necessarily make me feel unique, it does make me feel good I guess... and I do like art in all its forms (music, visual, etc.)
Do you want to feel "popular" by having a high post count?
This is a hard question, because I have a very high post count, but that's mostly because I don't use the chat a whole lot, so all my discussions are on the forums, which results in a high post count. As for if it makes me feel popular, meh... I don't think so...
Do you get a feeling of excitement to see the community's response to your thread?
Almost always, I like to get feedback on my threads, and so yeah...
Do you feel guilt when you do not post anymore after having established a posting trend?
Not exactly sure what this means
Do you feel excited to see the new threads people have made?
Some of them, yeah... New tournaments, new competitions, new PvP Events all give me a surge of excitement, some deck threads also give me a surge of adrenaline.
