Trying out Twitterfeed

Just read on cNET how to link my Blogger posts to my Twitter ones using Twitterfeed. Wondering how it will take my "longer than 140 characters" posts on Blogger and transmit them to Twitter? Will it slice them for me into appropriate lengths? Or will it cut them off with a "..."? We will see, huh? Ah technology...it's sooooooooooooooooo wonderful! ;-)
