Maybe I am too nitpicky, but I always get suspicious when people make claims about technology whose name they cannot spell right.
But yes, I also get suspicious when people can't spell a technology correctly. For example, anyone who has spent time reading some documentation will know that Lua is capitalized in title case, and not written LUA.
I am not convinced such pedantic measure of spelling is an accurate predictor of knowledge, to me it sounds more like elitism.
It's like discarding resumés which arrive with large food stains on them. It's just too easy to print off a clean copy, that anyone who doesn't must be a bit off.
