I agree that accurate and good info should be rewarded, but adding this stuff in the first place should also be rewarded, even if all the details aren’t there. Speaking from my experience, though relatively new to this site, you might try a new rum at a bar and not have all the details regarding what still, what process etc. However, by putting what you do know in the database, you at least set up a place marker so that others don’t have to do that, and can rate the rum. They’ve at least done half the work.
For some perspective, I’ve been rating beers for 10 years on Ratebeer, and now on Brewver since RB closed. The system there had it so anyone could add beers and admins would then verify details, filling them in if known. Now, the world of beer is much vaster and wilder in terms of details than even the world of rum–it’s often impossible to determine what hops is used in a given beer that may have only been brewed once and been on tap at few locations without a bottling. But it seems like the world of rum is getting more and more like this, with single batch bottlings and such.
All this is to say, I’m assuming what we want here is to have the most comprehensive database on rum possible. That means you will need people who add new rums whenever they see them, even if details are light in the beginning, as well as people who confirm and verify them.
Finally, this is a European-based website, so it doesn’t seem like such a problem in Europe, but for those of us based in North America, the database is pretty sparse in some cases. If you intend on improving that and attracting more continental American users, I think an “all of the above” approach on adding and verifying new rums is the best way forward.
Just my opinion, for what it’s worth.
