Sacha Chua is a lovely girl hacker who knows computer, manages her own Linux server and developes in Emacs. She used to be on Rackspace Cloud Servers but later moved to Linode because the price is cheaper there. Both are unmanaged, which means you have to be the server administrator all on your own.
Check out her article about this move and how she likes Linode: http://sachachua.com/blog/2011/10/decision-review-switching-from-rackspace-cloud-to-linode/
In my opinion, Linode is indeed a fine alternative to Rackspace Cloud Server, especially to people who don’t need provision so often and who don’t need to scale.
