Thank you for your kind words!:) Length limitation is there to teach the concept, to prevent authors talk about other topics. It might be a temporary thing but a needed feature for now. The comment/post feature was first implemented by Musing. So, it was an easy decision for me, but here we have a more customized and the first open-source version of it.

At first, we were upvoting entries in many other languages (German, Indonesian, Italian, French and so on), but later we have decided to concentrate on a small number of languages. Thus, we can use our delegation in an efficient way and educate the authors in the languages we know. In the next stages, anything will be possible with local Communities having their own moderation. As a criterion, we will just look if there are willing moderators and curators for them.

For 7-day limit removal, we plan to first separate "like" and "steem upvote" for a post, thus not all likes will mean a steem upvote and vice versa. As we aim for being a long term knowledge website, this might benefit our authors (and it was a requested feature).

I always make the same mistake on that word (eligible), I will fix the typo, thanks! Didic had proof-read the post, and it was one of the parts I added after his check:)
