I’m not sure Fluther generates the kind of revenue to allow for free t-shirts or charity donations. I don’t think they even pay the mods.
Lurve is just a way of seeing how many people have hit “great answer” on your quips and a little bit for how many people have added you to their fluther and for logging in each day. It’s a measure of experience with the site and of the esteem in which you’re held by fellow Flutherites. It’s a pat on the head and a thumb’s-up.
Can’t buy me lurrrrve…
