I've looked at WZ and a few others and here is why I always return to the 'Dise. In all the others, the conversation goes something like this:
Person 1: I think xyz.
Person 2: xyz?? I question your sexual orientation!
Person 1: Your mother keeps company with barnyard animals.
Here though, you get (usually) thoughtful discourse. We have some experts in cap-ology, draft-olgy, and even somebody with (some) medical experience who can comment on inuries and such. The conversation is generally respectful and almost always executive-like in its analysis.
If the merger means the talk degenerates into the example shown above, I for one, will miss what we enjoy today, and will partcipate much less, if at all.
