I agree with some of the points there - most of the content will be useful for years for the audience - and for now it means you will get a stream of end less followers - maybe a limited voting window is useful to make a fair distribution of the value within the community but 7 days looks like too short - I'd suggest to be carefull and not make huge changes on this but start experimenting - maybe with 10 days instead of 7 and see the outcomes, discuss with the community etc. resteemed
