If you don't use Google Reader, then I definitely recommend you get going and start using it! RIGHT NOW! I love it to bits - it enables me to easily add blogs I read (and manage them) and it's all linked to your google/gmail account! No more copying and pasting blog URLs into a widget and then losing it when you change your template!
Gosh, I hope I'm making sense here!
I use gmail and would never consider using any other email these days - I left my other email as soon as gmail came along 5 years ago. How convenient that Google also own/run Blogger too - this is how it's all linked and this is how you can insert (quickly and easily) your blog list:
1) Go to LAYOUT > PAGE ELEMENTS.
2) Click on "Add a Gadget" in the sidebar of your blog. Select the "Blog List" one:

4) Instead of adding each blog by the URL (time wasting, anyone?) you can either add the "Blogs I'm Following" or "Import subscriptions from Google Reader".

You just have to select which blogs you want and then "add" them.
The "Blog's I'm Following" are those Blogger blogs that you've clicked on 'Follow' (like mine?) and/or you can always import your subscriptions from Google Reader. Using Google Reader means that you can add blogs from any blogging platform and not just Blogger.
This is sooooo easy!
Most other widgets are really easy to move across to a new template but this makes easy work of the thing I always hated doing. Yay!
