Not worried at all about the bandwidth, just the copyright issues. They did the hard work (whoever "they" might be) and it's their content, so we should just point people to it. I am much more interested in hearing someone's opinion on an article they just read than reading it copied-and-pasted here. Post enough for me to be interested in reading it myself, and add your comments on why you think I should read it. [When I say "you" I don't mean anyone in particular, I just mean in general. If you're (anyone) asking me to go read a lengthy article, tell me why. I value your opinion.]
No ads, no donations. Maybe ads at some point for people who are not logged in (random web visitors.) And I will never turn down a cup of coffee at Grumpy's :-0
