a public – or white-labelable – rfe service a la uservoice, but easier to use

I’ve seen some services that utilize uservoice to handle requests for features, functionality, etc. And I have seen companies have formal Request For Enhancement / Enhancement Request / etc processes (generally culminating from support cases (hopefully from good ones)).

what to automate

I have been in the world of automation for quite a while. Specifically in the realms of server, datacenter, and cloud automation – but I’ve been interested and/or involved in other tasks that tend towards automation (even for a short period of time) for far longer than just my post-college time in the world of […]
