I find Silverlight less offensive and obtrusive than Flash, but probably not for the normal reasons. Since every single online advertiser out there uses Flash to make the most Flashy (no pun intended) ads to grab your attention, I promptly install Flashblock on any new machine I work on. Silverlight however seems to have too low adaptation for it to be useful or "bulletproof" for advertisers, so whenever I get on a site actually using Silverlight, it's for something I need or want (video, interactive games, apps, etc). I'm aware of that HTML5 covers part of that game pretty well by now, but still I find it non-obtrusive enough and generally don't mind. It's security-record and stability compared to Flash would be another reason not to mind it, but even to me, a techie, that's really secondary.
