WebTWFE: the second comming: You don't mess up with OLS. While traditional TWFE has received a lot of "but's" because its inability of correctly identifying ATT's, the methodology has been defended by Prof Wooldridge. His message is quite simple, but powerful. Yes, TWFE as traditionally applied, has many limitations regarding the estimation of ATTs.
