If you've ever struggled over when, how, and if you should charge for your content, Dan Loomis has put together another really useful post on the Big Ideas blog outlining how you don't need to pick just one way of pricing content for, in the case of associations, members and nonmembers.
He advocates for what he calls a "hybrid content strategy" that includes a mix of free-to-all content (older evergreen info, teasers for premium content, etc.); free or discounted premium content just for members; premium content for conference attendee eyes only (such as conference content for 90 days post-con); and some fee-only content that anyone can buy.
This is his second post on this topic lately, and I like this one even more than the last one.
