Goodmorning sir Hive account@favcau I don't know if the idea is isn't still enough for a micro suggestion.
but I added some more information in above post

Advantages

1. The advantage of having this feature is we could know some information for every contributors by reading their introduce your self profile.
2. we can easily differentiate the contributor that are new in open source project like me and those already have experience in contributing in open source project.
3. the main reason for this is we can probe on his introduceyourself post to see if this person is capable when recruiting new moderators or new team in the platform.

Disadvatage

1. it will add as another contribution and will add on the list of post that are to upvote but I guess 1% would be enough on the intoduction post.
2. it will occupy some space in the review feed and other than that I think theres no more disadvantage.
