I think ads would super suck. Who would want to advertise anyway? I don't think it helps BL as we position ourselves as an established, respectable outfit to have big flashing banners advertising rolling papers and insulin needles. If I'm not wrong, the current funding model is PBS-style pledge drives, and revenue generated by matching academics with our user base of people who are normally relatively difficult to find and engage in research. It's good to weigh up all possibilities, the site needs money to run, but in this case, I think that the cost to our public image and esteem of running ads would outweigh the monetary benefit. If someone with greater vision than me can imagine a way in which paid ads can work on the site, that's fantastic, but personally, I can't see that future.
