It looks like the most recent release for GrabPress (v2.3.6) improved the quality of the plugin dramatically. I love getting new video posts to my site, based on the exact keywords and video content sources I want.
For the feed I have where the search terms are more broad, I set the feeds to post to my drafts folder. On my feed where the matching videos are 100% on point, I have them set to post directly to my blog. No additional WordPress editor or curation needed, it's all automated.
For anyone looking for fresh video content every day, this is the greatest plugin.
