I have my TV connected to my cable box with an HDMI cable.

Every day, at least once per day, I will take one end of the cable out of the TV and plug it into my computer display. Then a little while later, I'll switch it back to the TV.

Is this bad for my TV? Would doing this repeatedly potentially damage the HDMI port on my TV (or on my computer display for that matter)?

Someone else is sure to know the exact number but the HDMI connector has a finite number of used before failure. While high enough for occasional use I think with daily use you have potential to ware out the connector. I'm going to make a wild guess and say 1000 cycled(500 in 500 out) but again this is only a guess, hopefully someone else will know for sure(I've seen it listed on AVS in the past and I was surprised how relatively low it was).

While I wouldn't worry about the cable wearing out the TVs connector is a different story. A couple options might be a short male to female cable or swivel adapter and keep the TV side plugged in all the time. If the cable or connector wears out, just buy another one. You could also purchase a HDMI splitter from somewhere like Monoprice.com, I don't think they cost much more than $20. MP also sells male/female cables and swivel adapters.

All mechanical stuff wear out. Heck I would do something about it just so that I won't have to get off the couch! No DVI? don't want to use Component?

Probably 10,000 cycles or more according to this article?

However, the danger might be more in the fact that HDMI is a communication line between the two devices it's connected to so plugging in with both units ON might cause a problem???

Nice find wajo I searched all over for HDMI connector MTBF(mean time between failure) with no luck. 10,000 cycles is sure more than I remember, in that case my biggest worry would be accidentally bending the plug as it was inserted, resulting in breakage(not wearing out) of the connector.
This is the type of extension cord I was talking about, for ~$4+ shipping it might be cheap insurance against accidentally breaking the TVs connector.

This is what I use to share a HDMI connection between a BD player and a laptop. Simple and works great.

Please keep topic titles SPECIFIC. See my edit. Thanks.

An HDMI switcher or HDMI extension cable will eliminate any possible issues.

Is 3 feet the shortest one they've got?

Why don't you search the site and find out for yourself?

Other than going with a angle type adapter I believe the above link the shortest they sell(6")

Yep, as stated above, there is a limit to how many times you can unplug and re-plug before the physical port will wear out. Best to get either an hdmi port saver (1 inch male to female), or just a 1-3 foot hdmi male to female. That way your port on your tv stays plugged in, and if anything you are only wearing out the 5 dollar cable.

OK I know nowadays even college kids rely on Wiki to write their papers... but what's the qualification of the author of this answer, it doesn't say.

If such component is made in the U.S.A., OK I believe it, but these days, it's most like made in China. Chinese stuff, they are no magicians, their stuff is so cheap because they have cheap manual labor, look at the iPad factory, stuff are MANUALLY assembled, not like the old days of automated robot-assembled (precised) Mac Fremont plant. So if they don't expect you to be plugging and unplugging the thing DAILY (reasonable assumption) then they will make it cheaper, cut corners etc. which should still be OK since they also don't expect that you will keep your TV for 10 years.

I wouldn't worry about the mechanical characteristics of the connections but the chance of a static discharge which can damage the electronics inside the units. All it takes is one minor spark to destroy both items.
