Recently memnotk (sorry mate, I don't know your real name!) wrote a definition of RSS on his blog. He incorrectly referred to the term as an acronym, and I politely corrected him.

Now, memnotk is not a native English speaker, so he can easily be forgiven for getting something wrong that many native English speakers get wrong every day. An acronym is a word formed from the initials (and sometimes some supplementary letters) of other words. For example, "radar" is an acronym (an abbreviation of "RAdio Detection And Ranging"), whereas "RSS" (an abbreviation of "Really Simple Syndication", among other things) is not. You don't pronounce "RSS" as a word - you spell it out when you say it.

Since then, memnotk has looked up the definition of "acronym" on an online dictionary and posted it to his blog. Problem is, the dictionary he used got it wrong!

This is very disturbing. I don't know how many people use Webster's as their online dictionary, but perhaps you should switch to a better one now!
