The SaidIt voting algorithm ranks "hot" & "top" feeds & sorts subsaidits. Is this algorithm public? Can less hot feeds be calculated, perhaps weekly, monthly, and/or interactively, rather than just "Hot Today"? I miss many good posts, have trouble keeping up, & find some bloom later. Comments?

A longer fade is doable. We have already modified the hot algorithm to be 4x less time sensitive than default Reddit. We could crank it up to 8x or something. If you push it too far though, it just becomes Top.

One thing I want to make clear. I do not want this to change "hot". I want this to be in addition to "hot".

Monthly seems too long but weekly or biweekly rather than daily seems better.

In fact, I'd also like to see a "extra-hot" or "hot this minute" to help diffuse the "pooling" in addition to the "hot today" and "hot this week".

I don't know if this is a pain in the ass or if it can be simply applied, in new tabs or perhaps in a drop down list not unlike the other list:

  • past hour

  • past 24 hours

  • past week

  • past month

  • past year

Except for maybe:

  • 2x Hot This Minute

  • 4x Hot Today <- current default

  • 8x Hot This Week

  • 16x Hot This Fortnight (maybe)

Is the algorithm easy to share? I'm curious what it looks like.

In the comment's "formatting help" Markdown table can you add a few more rows?

First new row left box (maybe after quoted text):

paragraph 1

paragraph 2

dash

paragraph 3

paragraph 4

First new row right box shows how just a "-" will skip a line:

paragraph 1

paragraph 2

paragraph 3

paragraph 4

Second new row left box:

dashdashdash

Second new row right box shows a division line:

Third new row left box:

hashtagHeader

Second new row right box:

Header

Please change the light yellow to a mid-tone so the light and dark text are both visible (ie. #888888).

yes, it's a pain in the ass to add, and I think 'top' is basically what you're after. If anything with a high vote count appears on hot, it will appear on top.

I have recorded your 'formatting help' improvement request.

This issue with the 'formatting help' box has just been fixed, I crossed it off our to-do list
