Me while coding: Hmmm... this isn't what I expected this piece of code to do. Me 1 second later: Wait, what do I want this piece of code to do? *confused about why I even wrote the code in the first place*
Perhaps unpopular and unconventional opinion of problems of peer review in science and academia:
Click to open/closeWorks published only in for profit journals inevitably have a conflict of interest and should be regarded as problematic for that reason. It also inhibits proper peer review. If a work can't be freely accessed and referred* to it shouldn't be regarded as a serious contribution to the scientific community.
* A reference to a work that isn't freely available is also highly problematic.
