Free software platforms, The good and the bad.

The Good:
They are free.
They usually come with a load of tutorials.
They are usually well supported by a large community.
Your website is as good as the amount of effort and time you put into it.

The Bad:
It can be hard to grasp the ins and outs of the software.
It might not be as fleshed out as paid software.
It might have bugs in the program.
No customer service.
