Thanks a lot for the quick reply! By 'meaningful' I mean 'show appreciation/like' - that's what is important to me, the other aspects come second.
I have a learning curve here - I find all I read about Steemit fascinating, but it's also a new way of thinking. I've got the impression (maybe wrongly) that most actions should be within the first day/24h (and the first 30 minutes). I'm glad to hear, as you say, that what you write can have a long life. So, I'll just upvote what I like - and keep on reading tutorials. Steemit is huge, and I believe in it. Your "yes" is enough to get this off my mind. Thanks again! (+1)
