My company a large number of small Wordpress sites. Currently we have about 10, but that number will eventually grow into the range of 50-70. We currently have a Linode for all of our sites, but it is starting to get unwieldy installing Wordpress and configuring it for every new site.
Anyone have any recommendations for hosting lots and lots of Wordpress sites in as simple a way as possible? Preferably we'd like the performance of a Linode with the ease of a shared host with a one-click install.
