My only major issue with Linode is their limitations of their stackscripts, and that they don't add and setup local IPs for their servers by default.

I would also like to see them use their Nodebalancers (Linode version of a loadbalancer) to expand across datacenters. It could be nice of them to provide an easier solution to load-balancing between regions so if I set up my app in each of their datacenters, and add a nodebalancer, they could help me lead the traffic to the closest source.

As for innovation they have added LongView recently https://www.linode.com/longview
