If you are looking for bounty site where you can get new bounty, I know of two website bountylord com and bountiesalert.com. however, the best place you can see bounties before uploading to the aforementioned website is bitcointalk thread.
Agree, it is still the main source. To make it easy, you guys can edit the URL page of the bounty section from the fresh post bounties to appear first and then old to the last. The other bounty sites is not a good alternative in my honest opinion, because it has a very low reward and they barely get any project in the past months.
If I am looking for bounty site I always prefer to use this forum the bitcointalk, because I know as bounty hunters I am sure that when the project launched a bounty program it here and managed by the reputed manager then the rest you can be assured that you are in a safe place. Once they have a bounty program here they just like filtered first by the DT members so I think that is the best for me.
