When you've been around a while and you're subscribed to as many people as I am, I think these could get really annoying really quickly, but I agree with having a more accessible subscription list. I rarely look at the homepage, and so I often miss things from people I'm subscribed to unless I happen to see it on the Recent Skins list, or it makes the pop reel. But maybe relocating the subscription list to one's profile would be a viable idea.

I agree, in my case, that the My Subscription Acitivity block is not that helpful atm for me, as I usually don't look at it that much. I'd like to see where this feature request goes, as if this gets implemented, my notification box would be lighting up a lot.
