Earlier quoted context omitted.
epigrammar works as sort of a nice play on words when you consider epigram. But epihub does not. Teachify is much better. The only point against it is it isn't very euphonious but then neither is epihub. Maybe edify, since it is already a word. But I think even so Teachify is better because everyone gets immediately sort of what your problem domain is.
Big Teachify crowd here! I will say, Epihub was really the byproduct of Epigrammar (as Mike highlighted above) and us just using the term “hub” a lot. It was hard to mispronounce, we had the .com, it felt like an homage to our previous work, and we didn’t think about it too much afterward. I do like Teachify though. It’s a pretty great name; I can’t lie.
Even though I also think that epihub sounds like epipen or something epidemiology related (especially in the time of covid) - getting a 6 letter dot comfor a nice prononceable name is not a small feat haha. That alone is a not insignificant number of points in favor of the name.
