Check out how many _times_ I have pointed this out.
(hint: perhaps one time a year on different fora).
I find it amusing that I was once taken to task for using "IE" (when that was very common in the "early internet days" to reduce typing to a minimum, since the then-common ASR-33 took forever to produce a single character when you were typing..) Yet the same ones complaining about IE resort to LOL, ROTFLMAO, IMHO, IMNOSO, and so forth, _none_ of which appear in Webster's unabridged. :)
Just goes with the territory of venturing into cyber-land where you run into all kinds, all the time..
Anyway, my last comment on the practice. If one has the time and inclination to be petty about spelling errors, there is little to be done for them of course...
Personally, "content" is more important than "presentation" most of the time...
