Why does Google Reader use up so much memory?

I'm running the dev version of Chrome and just found out I could see the memory usage of every tab (press shift + ESC to find out yourself).

Turns out the Shockwave Flash plugin uses 240 MB of memory and 27% of CPU while having open Google Reader. Killing this page brings it down to 50 MB. I reckon it builts up after reading through about 100 feeds.

So my question is: why does it take up so much memory and what should I do to diminish it?

Why I care? I often don't restart my browser (or laptop for that matter) and keep the Google Reader tab open for long periods of time. The memory does start to add up that way. Plus I have the feeling, perhaps incorrect, that it slows things down as well looking at the CPU usage.

Side note: using Chrome 4 on Windows 7 (32 bit)

I can't find it in Add/Remove Software, and I also can't install the correct version of Chrome… >>> More
