Considering how much institutes pay for journal licenses or the $20 - $50 I pay for a single article, I don't have much of an issue with $8 a month to find the right article.

Not to mention, you can still find articles for free if the keyword is in the title or keyword abstract so the $8 a month isn't necessary.

That said, I wouldn't mind seeing a rev-share model (like old platforms like Squidoo) for popular article authors who are sharing their work for free. With a growing amount of works coming from poorly paid adjuncts, while journals, publishers and institutions continue to rake in huge money, it'd be good to see some of this flowing back to the researchers who work to support the open access of knowledge.
