yes you can, feedmyinbox.com seems pretty popular, google search for "receive rss by email" for more.

but the problem is the google will only update the RSS feed at random intervals (usually a few hours inbetween updates).

so you wont be getting alerts as soon as new threads come out...

the only way to make sure you are seeing the latest threads is by opening google reader and going to the RSS feed, and pressing refresh at the top for force a refresh. thats the only way to make sure you have the latest updates without waiting for it to refresh itself.

so you can wait and get an email probably every few hours but if you want up-to-the-minute updates you need to visit the rss feed yourself and click refresh.
