That seems like an excellent offer! However it would leave me with significantly less SP, so it's something I'll think about. I expect that your offer will be snapped up quickly, but if not, I may take you up on the 2000SP offer. I will certainly take a look at @delegationhub, which I hadn't heard of before.
I completely agree with your thoughts on the importance of curation on Steemit, however I have an alternative idea for this. Firstly, I think Steemit could benefit from better organisation in terms of topics. SteemStem is a good example - if you enjoy scientific topics, you can go to their website and find a whole range of topics. If you're travelling somewhere new, you can go to the SteemitWorldMap and see all the posts written about that particular destination.
I'd like to see more portals like this, where newer Steemians could be featured and found via the topics they specialise in. It think the Steeve portal is focused on searching by topic, and there are also excellent search engines on other portals, like Esteem. Curation by topic is an important aspect of this. Good curation means that you know you're going to get quality when you go to the portal of a particular topic of interest.
Secondly, I think the 7-day payment window promotes frenetic production over quality. A longer payment window would allow really good posts to remain popular over time. It would be an incentive to post quality instead of shitposts.
