Not saying anyone is wrong or right here - but with the growing use of phones and tablets - I think that there are going to be more of these rather then less. I shorten things when having to type on my phone screen.
That said however - I myself have had to ask what some "site terms" are. But I just throw it out there and if I get a reply - I learn. If not - then whatever. I will look it up on Google or something. Nuthin to make my day worse fer sure!
