0utf0xZer0 is pretty up-to-speed on moe and tsundere, I think he knows that. He was noting that the 'moe' description in tvtropes is, politely, a mess and misleading. It is unfortunate the 'tsundere' descriptions invoking 'moe' link to it.
And yeah, I don't dispute the 'tsundere' entry isn't a good read for anyone before they start throwing terms around or wonder what "type a" means. I just see people sometimes quoting it as some unassailable source when it sometimes is as bad as the "Urban Dictionary" in missing the mark. I put a "credibility value" on all information... some sites rank better than others. It isn't unusual to encounter people who put '100%' on all sites la la la
(and yes, XKCD is full of win and has high credibility value
)
