It is a good idea to not posts all your blog posts on one blogger.com blog, and also post blog posts on Wordpress.com, and your own self-hosted WordPress blog on paid web hosting with a custom domain, and post your articles to forums, so people can continue reading some of your posts even if Blogspot.com is gone in the future.
Keeping a backup of blog posts is also important, so you can re-post lost posts to another website if Blogger/Blogspot is gone in the future.
Blogger/Blogspot is owned by Google. Google closed down a lot of their websites like Google Plus, Orkut Social network, Google Buzz, and Google Reader.
I think there is a chance that Google may close down Blogspot/Blogger someday like their other social networking like Orkut and Google Plus, and micro-blogging websites like Google Buzz.
