Blue lines between posts--different thicknesses

I just realized the blue lines between posts in a thread have different thicknesses. I count three levels of thickness.

Any significance to this?

Also I swear to you sometimes one of the lines goes from being thin to being thick, right there on my screen, no page reload or anything. Is that even possible?

In IE if I click on them, they change thickness sometimes.

No significance. At least that’s what the Illuminati told me.

Bwa-ha-ha-ha-ha!

For me too. Why? This has long bugged me.

It’s some sort of Internet Explorer weirdness. Not sure why.

Previous threads from as far back as 2004:

If I hold the mouse wheel down to scroll the page, the little circle and arrows icon leaves a mark running through the lines. Never seen that on any other sites. Very strange.

Cool! I did not know that.
