Some time ago the blogspot team just introduced a new version of blogspot. Now if you have a beautiful template, that you've invested some time in, you don't want to ruin all you work just to have the new version. What do you think about it ? To upgrade or not ?
I would upgrade because the new Blogger is much easier to use. You can drag and drop widgets in your template which makes it much easier to work with your layout - very easy for inserting feeds, HTML and such like. Also the new Blogger has more templates to play with.
