I'm active on Coursera - currently taking Game Theory II. Other courses that just started but look interesting include Cryptography, Computational Molecular Evolution, and Information Theory. I'm up to try one of those or any other quantitative course that looks interesting with a study partner.
Also, I have a decent background in data science/machine learning through Coursera courses but not much practical experience. If anyone wants to partner for either a competition (something like Kaggle) or to analyze a real data set, I'd be happy to work on that.
I quit the Coursera information theory one because it was presented so drably and gave very little high level insight into what was going on. It was essentially just the guy reading from the textbook. It's all the things wrong with traditional teaching with none of the benefits of MOOCs (aside from the forums).
I'm currently working my way through these lectures. The instructor is engaging, and actually explains what it is we're doing and why we ought to care. I'd be on board with working through them together!
For reasons mentioned in So8res article as well as for other reasons: studying with a partner can be very good. In November, Adele_L had posted an article for people wanting to find a study partner. It got 17 comments, but only 1 since November 16th. So I thought we (I) should make a monthly thread on this instead of constantly going back to an old article which people might (seem to) forget about. If people seem to agree with that, I will make a post about it every month.
So if you're looking for a study partner for an online course or reading a manual (whether it's in the MIRI course list or not) tell others in the comment section.
