This is a real problem - e.g. wikipedia link "pl:Józefów" is useless as it points to a list of about a hundred places of this name. With wikidata one can locate all similar cases and correct them - I have done this for Poland as well as for other countries, using Yuri's QA tool. Without it, disambig wikipedia links would stay there until someone accidentally finds one and will be willing to correct it. One by one. There were hundreds of such cases in Poland alone. > With practical applications i was referring to actual external use of > the data.

It is clear that this is happening. > The question is only how extensive such data transfer is. Yup, you are right, I can see now it's happening.
