I think there is probably a strong argument that there should be a dedicated local sub for Bangladesh/Bengali. It seems like there are bursts of posts that can sometimes result in more than 20 posts being made in a single day, but also there are times when several days go without a post.

The Bangladesh local language thread has more posts than the Hebrew sub has, and it rivals the number of posts in the Scandinavian sub. I looked through the last couple of pages of the Bangladesh thread, and recognized multiple people from my reading of English threads. This means there are people in the Bangladesh community making posts in English rather than their local language. There are probably multiple reasons for this, but I suspect it is at least influenced by their inability to create threads to discuss specific topics in their local language.
