I'm better at reading people online than IRL, more comfortable online, and I travel for work - so almost all my friendships are online. I don't think it's any more or less valid than IRL.
Have you ever had any incidences online where you misread people and fall out for a short period of time, Pyraxis? Compared to me, you appear (online, anyway) to have the ball in your court at all times without letting your emotions get in the way of things.
(Would you like to answer this query as well, McJagger?)
