Rusty Wright suggested a list of user keys to be stored in skill entity. But that means only 5000 users can have the same skill.
If you use the "Relation Index Entity" pattern as described in Bret Slatkins talk you can store 5000 users per index entity and an unlimited number of index entities. This will actually give you much better query performance too because you will not need to load the list of 5000 Keys every time you read your main entity.
The new release of Twig has direct support for RIE's and can actually let you query for multiple skills *in parallel* then merge the results and return the parents :
