Ask HN: If I 'Show HN', how many will visit?

Depends...20K visits if it hits the front page amd stays there a few hours??? If I remember from the past time I hit 1st that is...

My last three Show HN submissions:

3 points -> 10 views

1 point -> 25 views

1 point -> 24 views

None of them made it to the Show HN frontpage.

For a normal submission, the rule of thumb is 100 * upvotes. YMMV

12.
