Irrespective of how or where data was added, it will always become less
accurate over time.
The speed is dictated by, for fhrs data, how often establishments close
& reopen, not the form in which the data was added to OSM.
City centres, by nature of having a higher density of people, are often
better maintained than the wilds of the countryside.
The fhrs database is constantly updated (by law), so it's fairly easy to
regularly check when shops open & close.
The only conclusion to fear of adding data, by any means, due to it
going out of date, is to not add any data at all, and I'm pretty sure no
of us want that.

I'll agree that it is better to have a maintained set of data, but once it is
mapped it is easier to maintain. Locally I added Clacton town centre and while
I know there are some shops I currently need to resurvey I did do three the
other lunchtime when I went to collect my new pair of glasses. With Vespucci on
my phone I was just able to tap each building in turn to check whether it was
correct or not, and if not update it there and then (a couple of instances
where it needed more complicated editing I added a note and fixed those when I
got back). It is the initial survey and mapping which takes the time.
But out-of-date data remains a problem - after all look how many Lloyds TSB's
remain
http://taginfo.openstreetmap.org.uk/search?q=Lloyds+TSB#values
and the Lloyds and TSB names split in September 2013.
