"typo3 on linode" is a phrase I saw in my visitor logs as a search term used to find one of this sites pages. I can only guess that the searcher was wondering if TYPO3 could run on Linode. 

To answer that question, TYPO3 does of course run on Linode. In fact I used to use Linode for this TYPO3 site and it ran quite well on a Debian based VPS from Linode, one with 512 mb of RAM.

So yes, Mr. "typo3 on linode" dude, TYPO3 does run on Linode.
