The stats site that Ceirios mentioned does have that!
On the main page you can enter a “Creator username”, which seems to say that eteb3 was the author of 125 open Notes, the oldest of which is 7 years old! 
(That may also be last commented on?)
But going to the analytics page & scrolling down a bit to “Top resolvers”, you’re at #9 for the last 30 days, with 158 resolved, so we’ll forgive you! 
Not a ratio, but you can compare Closed vs. opened, and click on (Details) for individual monthly activity.
I would argue against creating metrics which would deliberately rank note closers over note openers - people who contribute primarily through StreetComplete shouldn’t be compared negatively to the people who resolve said notes, in such cases both the opening and closing of notes are equally as valuable contributions.
not really, given we have bottleneck at note solving
more note solving would help
more notes to be solved does not help at all
more high-quality notes is helpful but help is quite marginal
note solving in fact IS more useful than note creation (assuming that it is not closing notes randomly/blindly)
Note solving, yes.
Note closing, not necessarily.
Unfortunately some people do read “let’s close notes” and either edit remotely (disregarding the “This note includes comments from anonymous users which should be independently verified.” instruction) or close notes that are, in their opinion, simply old.
When you prioritize and/or reward closing notes, some notes will be closed for the sake of closing them. This might be fine in populated areas where any problems might be re-reported, but less useful in areas with fewer eyes on the map.
I think that’s a fair point. I have been closing some such notes (not all) when 1) I can see no way of resolving it without eyeballs on it 2) the value of the edit would be minuscule for the effort of doing so - usually because the edit would affect very few people
Chiefly these are anonymous notes giving details of a business (my bête noir onosm.org features a lot), or simply an address - inferably from a resident grumpy that Hermes (for that is the vintage of the notes) isn’t finding their property.
My experience of notes by novices is that they are usually far too coarsely placed - so even if not strictly anonymous , I don’t feel I want to just set a node at the note and copy the data.
And I am really not going to go 5 miles into the fens to check a door number. 
The alternative is to leave all these notes open. The trouble is it’s far easier to add a crummy note than to resolve it, so I conclude that we should wipe the slate of them.
But without any doubt, I am disregarding the instruction, as you put it, to verify the data instead. So I’m willing to hear that folk think I have the wrong approach.
Progress Report #2 - August
Hi all, in August we solved 5,401 notes (which is our second best of all time only behind July), so again amazing work from everybody, well done!
It looks like the Resultmaps chart[1] changed the July note count from 31,978 to 31,969 (perhaps this is accounting for any possible hidden notes?), and this taking off the 29,471 notes we had left open as of yesterday means we had a net decrease of approx 2,498.
Let’s keep on resolving! Thanks everyone!
