My personal opinion for the 'ease of use' would simply be to make it as easy for the community but also for the admins.
A script available to admins (or selected users) that generate a list with posts containing the #slothlysavers tag that has been published since the last time the script was run.
This list could then either be in a comment to previous weeks post, or be included in the current weeks post.
I haven't thought it through, that was just from the top of my head.
