not to hate on any new members on threadless, but i've noticed that a lot of the people who leave comments about a shirt design are members who have just joined recently. most of them have just joined threadless this month. member for a few days / weeks.
also, most of them are giving an average score of 4.0++ and have never submitted a design.
this isn't necessarily bad, but i wish that more experienced threadless-ers would leave their thoughts and suggestions about a design without being too sarcastic and rash.
