It's funny, just earlier today I was thinking how useful something like this would be. Even as an experienced developer, there are times when I'd like to bounce ideas off someone else for more immediate feedback.<p>Right now, I do that with co-workers, friends, and peers working on similar open source projects as myself. People are often busy, and time zones often don't match up.<p>$10 for 15 minutes seems to be on the high end of what I'd be willing to spend and really on the low end of what I'd be willing to charge. I'll probably give it a shot, but I feel like there needs to be more incentive to be a mentor (whether that be monetary or other).
I'm getting 69 uncached images downloading at 33MB total size. Takes 70s for page load on <a href="https://www.codementor.io/learn-python-online" rel="nofollow">https://www.codementor.io/learn-python-online</a>. Your scaling 2550px to 788px for me - perhaps on large retina displays this is worth while? IMO those 1MB images should be about 100kB.
