This 10 minute lock is really weird. Meaning of a post can change substantially depending on context, and the context continues to develop in the subsequent discussion. Discussions on the internet take place in a scale of hours, not 10 minutes.
As an example, a superficially likeable post turns out that it has shot over its goal and comes over as rude to other users in the subsequent discussion. While this post voiced arguments that I agreed with, its tone and perception make me later regret having “awarded” that poster a like.
It should be possible to revise likes, or to raise the limit to 1 hour.
