The best (i.e. most readable) way to emphasize a particular word in a post is to italicize or boldface the word.

However, entering HTML markup can be a tedious and, when I'm lazy or in a hurry, I frequently use UPPERCASE to EMPHASIZE a particular word.

Other options would be emphasize by denoting the word or phrase to emphasize with punctuation, /like this/ or *like this*.

BUT I'M NOT YELLING WHEN I USE UPPERCASE!!!! YOU GOT A PROBLEM WITH THAT??

Programmers are used to writing code in ALL CAPS.

Nope ... Wrong ... Even FORTRAN and BASIC is not written in all Caps anymore. But it is a Pain-in-the-*** to read legacy code in all Caps.

Princess Lurkin (daughter) emails in all lower case. It distracts from the communication, IMO.
