Highly relevant to the other thread about KYM by @bigtimbones.
I often find that most researchers have no idea what a given meme is, and will often use Urban Dictionary and KYM as their main source for definitions. Doing this with even the Oxford English Dictionary is suspect, not to mention the fact that UD is more or less aimed at giving the least accurate definitions.
The more sophisticated academics refrain from relying on KYM and the trend seems to be growing fast. At the same time, KYM (and other meme explainer resources like Lessons In Meme Culture or Internet Historian) really do fulfil an unmet need; it's evidently a major need. I think we could develop a better method of doing this without attempting to be encyclopedic if we took a more conscientious approach with regards to the ontology.
In my opinion, it's something we could even develop organically as an outgrowth of discussing individual memetic artefacts (e.g. individual image files) as case studies within this forum.
