Blendle founder here. It's exactly what we're working on (making articles for free on Blendle if you already have a subscription), and are already doing ("blendle links") :)
Awesome, I look forward to you becoming the "Google Reader" of pay-walled content. :-) It has always been a challenge for me that I would be happy to pay for an article but rarely want to commit to a monthly fee without knowing if I'll use it enough to make it worthwhile. I really love that you guys have taken this sort of thing and shipped product.
