1) Go read some Gamasutra Sales Analysis between XBLA & PSN
They don't seem to have any current analysis equating the two platforms, so I'm assuming there is no hard data you are basing your claim on.
2) Considering Microsoft's entire company mantra is about going Digital (and extra why they received so much blowback), you're just deluding yourself if ou think Sony is pushing Day 1 Digital more than Microsoft.
Microsoft's "company mantra" is irrelevant, "Day 1 Digital" on the PS3 seems to play a much bigger role than Games on Demand sales on the 360. Sony is regularly offering special editions, pre-order bonuses and similar perks not found on GoD.
Sony is also often advertising their digital day-and-date with retail ("AAA") game offerings, something Microsoft doesn't seem to do at all - or not even offer.
3) When did anyone mention retail software sales? (In which case they would still be more skewed towards the 360, but again no one brought those up)
I mentioned them as an additional point of data.
4) Purposely being obtuse or just lack of reading comprehension? I was explicitly talking about the recommendations section of the dashboard which is about actual content that applies to the user (DLC for their games, newest XBLA releases, demos for top games, etc...)
..., McDonald's wraps, steak houses, car rentals, ...
People are deriding the indie games store because it is separate and not on equal footing with their other game stores - which means indie games are at an inherent disadvantage in terms of discoverability. It's not about ads on the dashboard, but about the layout of the store and its search function.
