Merging similar threads.

[kato13]

We have had success in splitting wildly drifting threads. The "Ruins of Warsaw mass combat?" thread made me consider merging very similar threads. The one downside I see is that it might stifle conversation if people think we have already covered a certain subject. An occasional revisit of even well covered subjects can bring up valuable new information.

The other option which I already did is to link the similar threads. Does anyone have any opinions on this? Can anyone think of positives or negatives I might be missing.
