Why the down-vote? You don't rotate your logs? Thought it is commonplace. Rotating logs includes compressing old ones. Or are your log files actually over 100 MB? Why? What are you printing? Output of "yes"? :D

As someone mentioned, Emacs is over 100 MB, so it does not have to be hypothetical. That said, I use emacs (and vim) interchangeably and I have nothing against it. I have LibreOffice, too, which is also a behemoth, but so is Haskell with its modules that I see getting updated regularly. In any case, I still prefer KISS and the fewer bloat as possible.
