I just noticed that "the over a বছর ago" thing has been removed. Now, they actually appear how long পূর্বে it was পোষ্ট হয়েছে অথবা commented. Is it just me অথবা what??

This was changed a while ago. I think it's an improvement, because in the case of duplicate সংগঠন it makes it easier to see which is the original - normally the one with oldest content. Plus sometimes it's interesting to see when something was added, অথবা how long it's been since a club was really active.
