which way will the balloon travel?

I've driven with helium balloons in my car. Their motion never stops seeming odd, even when you've sussed out the reason for it.

I hate it when people post a link and think they started a worthwhile discussion.

The reality is that if they don't think it is worthwhile providing enough details about what is found at the linked page then their so-called discussion is hardly worth the effort.

The link should be for additional information, not primary information.

One particular problem I have seen on many occasions when someone posts just a link is that there is often one or two particular points at the link that they wish to discuss and then get ticked off at people who discuss some other point. When that happens, it's their own fault -- all they had to do was to start the discussion instead of just idiotically posting a link.

Besides, what do you think happens when the link changes? A year from now, someone might run across the post and want to find out what the discussion was about but can't because the link is dead. If the original poster would have had the decency to start a discussion and posting the link only to support the discussion, then it wouldn't matter as much when the link goes dead.

If it were up to me, the policy would be to delete every thread started with just a link. Try spending some of your time starting a discussion instead of posting a link.

Try to imagine a truck carrying clear plexiglass cubical containers of water. Imagine the water has floating objects in it. Then the truck accelerates. The water slooshes to the rear wall of the container. That causes the objects to go forward.

Then the trucks hits a constant speed on the highway and the water levels out.

Stretches your mind to imagine the whole thing.
