I use my Twitter as a way to communicate things that I wouldn't be able to on Youtube or forums. A bit more private and personal stuff (such as music taste, unlisted videos, etc.) , but not personal enough to warrant private messaging.

That does happen after a season ends, but this time around it ended while school was going, I bet during the summer things might kick back up again, then when the next season pops up we shall see many more.
