About Spark...

Are Sparks something that is worth keeping?

I have always wanted to integrate the code myself and I don't really like the magic, I have to maintain it, so I need to know what is where and how it works.

I see how this could help, but if you are on shared hosting or have no command line, most of these package systems are more trouble than they are worth.

Please don't think I am against them all, I use compass, node.js etc. in my development environment, but that is deployed on mass to the live server, so it is functionally useless on the live server anyway.
