IAWYC, but ISTM that it's not that much easier to type out the whole phrase when using computers, unless you've got a lot of custom macros going. And in the LCPW, context should be enough for acronyms, though naturally YMMV.

ETA: OK, that really doesn't work here, but I couldn't resist.
I posted this in the comments at Eric Raymond's blog:
Then I realized some here may find it useful.
Extensive use of abbreviations and acronyms was primarily a convenience for writers, when writing was done by hand and then by typewriter, there is less justification for it now when most writing is done by computer. And as my comment points out it is usually a negative for readers. It does benefit readers when you can convert a long phrase into a readable word, SCUBA and LASER spring to mind, but that doesn't occur often.
