is snsd/girls' generation taeyeon's twitter account (@Taegangers) really taeyeon?

i recently started to follow girls generation of twitter. and i noticed that many of them tweeted in english...i wasnt surprised by tiffany or jessica....but taeyeon really caught my eye.....she was tweeting in english and she was tweeting at the most inconvenient times. korea is 13 hours ahead of canada...and she was tweeting in the afternoon for us here...which meant it was way past midnight there. so i was wondering whether it was really her....does anyone know?

Taeyeon? I believe the ones who got twitter accounts are Seohyun and Sunny. It probably Taeyeon's roleplayer. Taeyeon only made an Instagram account.
