Thank you!
I have to admit sometimes I do struggle to find the right tags for my posts, being new and still trying to get some reach I always try to use all 5 tags.
Also I do look at the most upvoted/highest payout/most visited tag list and try to pick the highest ones (well... the highest once related or closely related to my post)
I think in a post or 2 I might have added a tag that might not be considered closely related enough... But I am not sure, fellow steemians will have to be the judge of that.
That being said, I do agree with you, I do quite often stroll trough #introduceyourself to welcome 1 or 2 new steemians as it felt very welcoming when I started.
(That feeling did diminish a bit afterwards when it became clear that the majority of those replies are (or look like) auto-bot replies... but none the less, at that moment it felt welcoming)
