best-of-craigslist is a collection of thousands of postings CL users over the years felt were hilarious, bizarre, heartwarming, poignant, memorable, or just plain awesome.
Clicking "best of" next to the heart at the bottom of a post nominates it to be considered by staff for inclusion in best-of-craigslist.
If you just want to bookmark a posting for your own reference, use the "favorite" button (the star next to the post's title).
Please note -- clicking "best of" does not improve a post's search ranking, increase traffic to it, decrease its chance of being flagged down, or otherwise help or protect it.
Voting repeatedly for the same post, or for something that is clearly not "best of" accomplishes nothing (at best), and may result in the posting being removed.
