I actually had to Google Google Reader to get to it, I looked this week in my list of apps or whatever from Google and it isn't anyplace to be seen. I suppose they don't want people going all wild and subscribing to feeds. Bad dogs.
I enjoy my current blogroll and have been tweaking it lately. It has my many interests pretty well covered. I am at 85 and I could be mis-remembering, but I think the limit is 144 blogs in the roll. Keeping an eye on it and will let you know.
