Thanks for raising this question again.

Recently, I've had an experience where someone was zapping my posts and comments witn 1 sat again and again. TBH, I don't why buy I felt bad. I didn't say anything to that stacker at that moment because he must be a newbie stacker. Then, I also remember how I used 1 sat zap for two weeks in the beginning!

The arey of zapping is certainly one thing that new stackers must be guided towards in the beginning.

Currently, I've increased my default zap to 21 to whatever I read in comments and 100 for good posts. I think the zapping should not be fixed. However you should zap whatever you read, that too at least 10 Sats. 10 20 100 and 1000 also for very good posts. Yrs you're right zapping should be done with responsibility, responsible towards newcomers. I zap on Bio posts of new stackers and post a few links from @Natalia. To improve engagement here I'm also zapping daily top posts and comments on a regular basis. And believe me it's more rewarding. Recently, I've been in top 5s on the leaderboard and I attribute it to more zapping, rather than just being more active here. Please don't take it as bragging, I've got to the top of leaderboard just yesterday. SN says, zap more and take back your reward.

So, I urge everyone to please zap as more as possible to encourage engagement here.
