internet usage at school

i'm regularly on myspace or various forums i'm a part of while at school. i see absolutely no harm in it, especially since i get good grades and tend to prioritize my schoolwork before internet fun. i do my homework first, but there's so much free time, that it's often the only thing i can think of to do to take up my time. there's no harm in it unless it prevents a student from getting their work, but most linworth students are responsible enough to not let internet usage hurt their grades.
i could certainly understand why a staff member could take issue with this or even feel offended or insulted--they may feel that schoolwork is being neglected or academics are not taken seriously enough. they may feel that myspace is more important than stuff for class, and that could offend some teachers. but honestly, almost all the kids on myspace at school are on there BECAUSE THEY HAVE NOTHING ELSE TO DO, meaning all their work is already done. i personally live in the powder room, it's my place to hang out at school, and pretty much everybody gets onto myspace at some point. and the ones i see in there the most are the ones who are quick to get their work done and have consistently good grades, if that's believable.
if a kid's grades are terrible and a staff member sees them on myspace, then i see reason to take disciplinary action or get upset. but if a kid is just harmlessly checking comments and messages on a networking site and they have all their homework done and an A in your class, are you really going to have the nerve to bitch at them about it? i've been at linworth for 2 1/2 semesters now, and as a powder-room kid, i can honestly say that i have never seen a kid on myspace refuse to get off if someone has legitimate work to do on that computer. if it's during a high-traffic time, and someone walks in saying that they need to do work, there are usually 2-3 people who immediately offer "oh hey, i'm not doing anything important, you can use this", and it's totally fine. students at linworth DO understand that schoolwork comes first and myspace and facebook are fun things to do to take up their time when they have everything done.
