As far as Sony goes, the visibility Sony gets on this site doesn't seem fair for other brands doing a great job out there as well. Michael is pretty open about the relationship he has with them which is OK, so I am not interested in conspiration theories. All I am saying is that there is more than Sony out there and again, my high hopes for LL call for a broader focus.
The material that gets posted on LuLa is what Michael finds interesting.
There was a time when news about Canon products featured heavily - that was because he owned Canon gear and was interested in it.
Then Sony came out with the A900 and friends and it appears that this became more interesting to Michael than what Canon was doing.
Going by comments I've read in various stories, at an earlier point in time it appears that Michael owned and used a lot of Nikon equipment but then Canon did some innovating with their lenses and he switched.
I'll add that what Sony is doing - by innovating and doing new things to capture market presence - makes their products generally more interesting than say Canon, where things change and slowly evolve rather than any sort of revolution.
Imagine that he'd stuck with Canon. There'd be nothing written about the NEX or other m4/3s yet these cameras would be the new kids on the block. If you were running a photography website, what would you rather be doing? Jumping on the coat tails of Sony and their daring to innovate, wherever that may go, or sit in a nice cosy Canon box and then one day find out that you should have gotten out a long time ago for more interesting content?
If you feel that there should be more Canon stories, then look to Canon for interesting and innovating products. On wait, there aren't any and haven't been any for a long time? Who's to blame for that?
In the last 12 months, there's only been one real feature that has caught my attention from Canon - the ability of the newly released S100 to apply multiple white balance settings in the same shot.
