As a birder I have thousands of bird photos and would pay for this service.

For organic chemistry graduate students and professional organic chemists, all this stuff will largely be so ingrained as to not to require these kinds of resources.

There are, however, a large number of people who are in chemistry fields who need occasional refreshers on introductory concepts and for that purpose, these are excellent.

On the other hand, by the standards of what an undergraduate organic chemistry student is looking for from a free online resource, and given that it is just one guy doing this, in his spare time, I think this is absolutely fine.

(I have a competing website on organic chemistry and I think this guy does a much better job on graphics than I do.)

About 10 years ago I visited him in his studio where he had all mocked up in paper and cardboard, putting all the pieces together. Fun to see it finally out and in people's hands.

"If you can't reproduce a procedure in Org Syn, it's YOUR fault" - my PhD supervisor

Been doing this 12+ years, mainly focused on teaching sophomore organic chemistry. Started as a blog, don't know if it really qualifies anymore as I've organized many of the posts into chapters that follow the typical order of topics as taught in most North American schools. Still write rants from time to time

My kids (10, 8) earn "check marks" for each 20 minute chunk of time they spend reading it, which they can trade in for various goodies. Usually before they go to sleep

Edit: Also, they have used it for school projects. 2nd grader had projects on Poland, Neil Armstrong, and pygmy rattlesnakes this year. Very handy as an introduction to a wide variety of topics.

These can be the saddest cases in my opinion. Lower downside, but lower upside too. You work your butt off and knock the ball out of the park with your project: who notices? A few experts, in a very narrow field, may recognize the significance of what you've done. Can be lonely.

One got tenure and became more mellow in a relative sense. The other was subsequently unable to attract any more graduate students to their lab, and left for another, slightly less prestigious institution.

I am also familiar with one case of graduate students resigning en masse, leaving a PI with a hollowed-out research group of 2-3 that they had to rebuild. Prof had a subsequent attitude adjustment.

In all these cases the stories spread pretty quickly and profs realized that there were costs to abusive behavior. These stories pre-date social media BTW.

With an assistant prof you will be asked to do unreasonably long hours on ideas that haven't been fully validated, but you get a lot of face-time with the PI (for better or worse) and have a chance to get on the ground floor of a potentially great research program. Your boss has a lot more invested in your success because their career depends more on you. It can be exciting.

With a more established prof you are more likely be plugged into the n-th iteration of an established research program. You're more expendable because the prof has more options to hire your replacement; you can get lost in the crowd; the prof won't be in the lab as much (travel, service responsibilities) so it's more sink or swim. Lots can go wrong in this environment. As the group gets larger, internal politics can create frictions, especially if the supervisor is away a lot.

I see A) as better than B) but that is just me.
