In this particular game, how is 28:Nb6 a blunder ?!

Here?

Because Nb6 allows a dim future where the white kingside roars.

As opposed to the alternative where the white kingside goes nowhere and the queen side pawns are gone.

After ....Nb6 black will soon lose all his kingside pawns.

But I won, there for it was not in fact blunder. 

Because White's bishop can then have Black's Kingside pawns for breakfast.

It was a blunder. The fact that your opponent was a worse player than you does not change that fact.

No blunder, very fast analysis of a computer on here. To make it a full on blunder I'd have to run it through Rybka 4, which I don't have yet.

I get it. You mean a blunder is dropping  pieces, not pawns.

Then why you need computer analysis when you can recheck visually whether you drop pieces or not.

I didn't blunder since I won, also far ahead of time.

You won, no blunder, perfect game. Got it...

And also, Rybka 4. is not the best. It is currently no 25 in ccrl.

Rybka 4 is an extremely old, weak and outdated engine.

At your beginner level, people who do 10 blunders usually beat the other one who do 15 blunders.

A blunder occurs because you make a move that suddenly drops evaluation by a very large extent. For example, allowing pieces to hang. However, since you won, it is very likely that either you had a massive advantage earlier and made a blunder (but you are still ahead), or you really made a losing blunder and your opponent counter-blundered to return the advantage to you.

Time is not a factor in determining blunders, but they do affect human play. If I won a game on time in a position where I have one pawn left and my opponent has two queens, my analysis will definitely show lots of blunders made by me.

Okay guy's and girl's, after all it was a blitz game. I simply understand how 28:N6 was in fact truly a blunder ....

What this old chess engine/Computer ? http://www.chessgames.com/perl/chessgame?gid=1242850 Hah ! 

Winning is all that matter's. 

Then why did you even create the thread and ask the question? Did you just want some attention?

"Winning is all that matters" is the sort of attitude that's gonna mean you hit a brick wall and stop improving pretty damned fast... I've learned more from my losses than anything else. I've learned a lot from wins where I blundered too. The fact that your opponent *didn't* punish you doesn't mean they *couldn't* have done. That blunder matters especially if all you care about is winning because noticing it and making sure you don't make similar mistakes will avoid losses against stronger opponents who absolutely WILL punish your mistakes.
