I couldn't have said it better myself, so I'm not going to try. Forgive the extended block-quote!!
7CM Blog: "In reality, you can do almost anything with Blogger that you can do in “superior” packages, with a little bit of ingenuity.... Most importantly, don't put off blogging because you 'heard' stuff that makes you think Blogger may not be fully 'up to the job' or because you are waiting for the perfect tool for anything to come along. As with everything else on the road to success, just get started. Blogger is perfect for that."
