If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
Er... yes.
I suggest that this sort of dismissive response is only marginally less helpful, and much ruder, than no response at all. How about "Yes, it's very different; e.g., in the one case X and in the other case Y, which is incompatible with X because Z." Or, if your time is really so precious, "Yup, completely different; sorry, no time to explain why right now.".
