Excuse me, do I really think that 3 invites per day for the whole Habr is negligible? If you lower the bar for issuing invitations from 100 points to 50, then there will be three times more invites.
There are a lot of people who want to get an invite and there are intelligent people among them who, although they don’t bother to write a big topic for the sandbox, would be very useful as commentators.
Also, once a year I would distribute invites to those who were active and behaved well in the outgoing year. For example, to all users with positive karma, who wrote 50 comments for this year. ')
What do you think?
