What the heck?
I appreciate that the duolingo team is always working on improving this site, but it's quite frustrating when helpful portions disappear. First the genders in the vocab lists, and now it looks like two whole lessons have been scrapped during the new lesson update. Please bring back the lessons and the genders. This is for german, btw.
Understand your concerns, don't worry! We're figuring out the best tree model (sometimes this involves experimenting with different amounts of skills and their layout). The trees will continue to evolve and improve and so will the vocab page. I agree the gender hints should be reinstated. Thanks for bearing with us! :)
For anyone learning English, "heck" is a word that is traditionally substituted for "hell" to keep one from cursing, been around a long, long time. Often considered rural in origin, to me it seems very similar to a Dutch word, "Gek" which means "crazy", and in Dutch sounds like saying "heck" while getting ready to spit. Lot of Dutch settlers in the old days in America.
