Yes, there is a lot of free information, however, there is no other place on the internet that people can get the kind of advice they get here, for free. Sure, there is reddit, for those who don’t mind wading through a lot of garbage and a large number of people who have no idea what they are talking about. I honestly can’t think of anywhere else on the internet where people can get a great response most of the time just by asking.
There are other sites that have good information, but frankly it’s this forum that makes CC so valuable.
I’d pay a fee for a subscription, mainly because I like using this site to keep abreast of what’s current both culturally and in terms of policy developments in the industry. This site helps me remain up to date with higher ed, which is relevant to my work. I also like helping students and parents navigating the process, but it is completely understandable that people don’t feel they should have to pay to offer free advice.
I am a realist. I think a subscription fee would put off a lot of the more casual users who still have good advice to offer.
I’m probably one of the few people that doesn’t mind ads on CC. Ads are just part of life and CC has to earn revenue somehow. The only time I have ever found ads to be troublesome was probably about 6 years ago when somehow there were pop up ads featuring scantily clad women.
I think the subscription fee would have to be no higher than $50 a year, but I do think it will be a hard sell and that they biggest loss would be the casual users, as I mentioned.
Edit: I think some people here have made some great suggestions on ways for CC to earn money. To me, approaching the colleges seems an obvious option.
