You should publish them! A blog post doesn't have to be wholly or even slightly novel to be immensely useful for someone.

Right delivery, right place, right time. Others will almost certainly have thought, discussed, written about the same ideas before you but the reader might not land on their blogs or equivalent, and even if they do, the delivery might not speak to them.

They might however land on yours and your delivery may be just right for them.

Anyway, nobody owns ideas - to the reader, whether it's you or someone who thought of it before you delivering the idea doesn't matter - all that matters is the delivery of the idea itself.
