Thanks for your response. I was hoping for a response from one of the staff or someone here who has had more particular knowledge of this area. It just seems odd to me that one can lose to a much lower rated player or win over a much higher rated player (as the case may be---I think he only lost 11 points) and not have a larger gain in rating.
It depends on the rating deviation of you and your opponent. If your opponent has played fewer games, your rating wont change as much as if they have a stable rating. Also, the more often you play, the less your rating will change.
Once your rating becomes fairly stable, you wont see big changes from single games. That's about the most you will ever get now from someone in that rating range as that opponent had a very low Glicko RD (29).
They use the glicko rating system, and you can find your rating deviation in your stats, and also see how much your rating will change before entering any game.

I figured it had to do with the R.D. Mine is 43 and you say his/her's is 29. I'll check out the link you gave and see if I can figure out what these respective r.d.'s mean in regard to the question I posed.
OK back from checking out the wikipedia article (the intro actually). It says, "A higher Glicko rating implies more skill playing chess." But then later on it says, "After a game, the amount the rating changes depends on the RD: the change is smaller when the player's RD is low (since their rating is already considered accurate), and also when their opponent's RD is high (since the opponent's true rating is not well known, so little information is being gained)"
If a higher R.D. indicates a more skilled player then why is a higher r.d. also not considered as accurate. If its not as accurate as a lower r.d. but a higher r.d. indicates more skill? Do you see my puzzlement?

It's not a higher RD (rating deviation) indicating a more skilled player, it's a higher rating. A higher rating deviation means their rating isn't as likely to be as accurate because it's based on fewer recent games.
The rating deviation basically sets the upper/lower level of your potential 'true rating/playing skill' when added or taken from your current rating. I believe 2xRD is a 95% confidence interval so for example with a 1200 rating and an RD of 25 your 'true rating' will have a 95% confidence of being between 1150 and 1250.
@Scotty, that makes it easier to undestand. Better than the "official" explanation. Thanks.
Well here's an even stranger situation with my rating. I went into a game with an opponent rated 1289. My rating prior to this game was 1228.
OK. Now I won this game against the 1289 and my rating went DOWN to 1210! Can anyone explain that?
the lower rated player will only gain a few points but the higher rated guy will drop like 50 or more I've seen it happen and dont know why it is.

That's very interesting. I can't think of any reason for it. It must be a bug.
I think so too. A bug that is. Who and how do I report this just in case it is a bug? Anyone know how to "bug" the Staff? 
Please be relevant, helpful & nice!

Are you talking about turn-based chess games? That's the only way I can understand your thought. This is Standard Live Chess.
The ratings I gave were what we were rated at before we played, my opponent and I. He was rated, before playing me, as 1289. I was rated 1238. After we played our game his rating went down to 1279, as one would expect, losing 10 points. I should have gained 10 points judging by what usually happens. Instead my rating after the game went down to 1210! That's just weird. Not only did it go down after a win, but it went down after winning against an opponent who was ca. 50 points higher!
Lastly I don't understand the blank responses above. What is that about?
Yes I have a question. I was rated 1183 going into a game w/ a 1299. I won and my rating went up only 11 points?? I had thought it might go up more since the difference in our ratings was over 100 points. And yet only 11?
