> I do feel reluctancy answering to a post even a few hours ago thinking my answer might not be applicable to their context anymore. But not knowing, I believe keeps the conversation going for a while. I see it actually taking place.

First time I hear about textlog today, seems interesting (and good to remove likes etc). But if there aren't other comments that already address whatever point I would want to make I dont care if it is 10 minutes old or 10 days old (now, 10 years might be different and probably should be different).

Maybe that is due to my background in forums focused on solving technical problems (troubleshooting, programming, etc), but even if the original poster helped by my input any longer, someone else might be even if that is years down the line, so answers are always useful.

Of course context is everything, and if it is someone talking about what they had for lunch, that is irrelevant 10 days later (but I also wouldn't be interested in that content to begin with, even if it was 10 seconds old).

So in conclusion, I think having a timestamp is useful, and definitely for older posts (but for newer posts I think you are overestimating the problems of having them).
