This.

"If White can somehow convince Black to push his d-pawn to d4, then all his problems will be solved.  Cheesy

7...d6 8.ed6 (otherwise ...g6 and ...Bg7, followed by a timely ...de5 will leave the e5-pawn weak) Qd6 looks favourable for Black, who can follow with ...g6, ...Bg7, ...0-0, ...b6 and ...Bb7 with a better position. Eventually Black will occupy the d4-square with ...Ned4 and blast open the position for his more active pieces with ...e5. " - TN

Also this.

Short answer is that White has space, while Black has squares.  If advanced pawns aren't preventing you're opponent from activating his pieces (and White's aren't), they're not helping.

If White can somehow convince Black to push his d-pawn to d4, then all his problems will be solved. 

7...d6 8.ed6 (otherwise ...g6 and ...Bg7, followed by a timely ...de5 will leave the e5-pawn weak) Qd6 looks favourable for Black, who can follow with ...g6, ...Bg7, ...0-0, ...b6 and ...Bb7 with a better position. Eventually Black will occupy the d4-square with ...Ned4 and blast open the position for his more active pieces with ...e5.

1) Black's e6 Knight is not clumsily placed.  It would only be clumsy if it could be kicked around or got in the way of the development of the other pieces, but here both Bishops can be fianchettoed or the Knight can hop to d4.  The Knight is very well placed.

2) Starting a pawn storm with moves like g2-g4 will be very double edged; White will be getting further behind in development and his King won't have a safe place on the board.  Also, Black can possibly play ...h7-h5 if needed to hold up a pawn advance.  In general White's pawns are NOT impressive.  They are immobile, and immobile pawns are almost always weaknesses.  They aren't taking away any squares from Black's pieces (both of his Knights are happily sitting near the center).  Black's light squared Bishop can go to b7 (look at that beautiful open long diaganol!), which will be especially tempting if White moves his g-pawn.  The dark squared Bishop can go to g7 or even h6 to put pressure on the f4-pawn (possibly combined with ...h7-h5-h4 if White replies by g2-g3).

3) White does have development problems; all of his pieces will be very passive.  Black won't let White play f4-f5, and both of White's Bishops lack good squares.  Also, where do White's Rooks belong?  I don't know.  Black will be able to initiate a pawn break wherever he wants (in other words, he'll be able to open lines wherever suits him) with moves like ...b7-b5, ...d7-d6, ...f7-f6, and even ...g7-g5.  Black has the luxury of opening lines wherever it will be most uncomfortable for White, whereas White doesn't have the chance to open lines himself.  This means that Black can take more time to improve the position of all his pieces and White will essentially run out of useful moves.  Black will end up with a kind of development advantage in the area of the board that he chooses to open.  It might sound far-fetched, but that's the luxury of being the person who makes all the decisions on when and where the position will open up.

4) Black's chances for attacks will come after he's developed and chosen an area of the board to open; see above.

5) It's clearly best to fianchetto here because it's the only way to get the Bishop into the game!  With the Knight sitting on e6 it's not going to be developed the other way.  Also, Black probably doesn't want to play ...Ne6-d4 early on because White can relieve his cramped position with exchanges.  Yes, I called White's position cramped.  Optically he has more space, but in reality he just doesn't have any good squares for his Bishops, Rooks, or Queen.

In a way, this position reminds me a lot of the Tal Gambit line 1.e4 c5 2.f4 d5 3.ed Nf6 4.c4 e6! 5.de Bxe6 6.Nf3 Nc6 7.d3 Be7 8.Be2 0-0.  In that position, it looks like White has more space because of the pawn on f4 and the extra pawn on d3, but in reality his pawns just block in both of his Bishops and White's game feels very cramped to me.

A few points just after a quick glance:

A)What Rybka thinks is not so important

B) White has committed his pawns. Remember, pawns can never go back! Black is staying flexible to see where his pawn break will be most efficient and when he finally makes his pawn breaks, chances are good some of whites pawn will be weak or leave weak squares behind. Can you see any weak squares in black`s position?

C)Theres already one obvious weak square in whites position: d4. The knight on e6 is excellently placed to use that square.

D)A fianchettoed bishop is often a strong piece, controlling the longest diagonal on the board, among the squares it can cover is the important central squares! Entire openings has been developed based on such a bishop. Besides, the fianchettoed structure and its bishop can strengthen the kings defences. Here it is also the most sensible way to develop. 

E)If black stays flexible and hurries with his development he doesnt need to do any special attack, just set pieces up for a pawn break and play the pawn break when whites weak squares and committed pawns will tell.

F)After 7..g6, f5 is stopped and if white tries some crazy g4 based stuff he is getting dangerously behind in development. I imagine something like 8.g4 Bg7 9.f5 Nd4 (that weak square),  castling and d6 should be very good for black.

G)White has some issues developing his bishops efficiently. The d3 pawn is getting in the way of the white-squared bishop. The black-squared bishop has some similar issues.
