This is "asking for it", as they say, as there's nothing that gets<br>
programmers going more than a good discussion of tools :-)<br>

I'd turn the problem around. What are you trying to do, and why are<br>
you set on using Erlang for it? "Learning Erlang" is a perfectly<br>
acceptable response, but it does color the discussion some.<br>
<br>
I've been doing "web stuff" for nearly 20 years, and here's my opinion<br>
about the state of Erlang and "web stuff":<br>
<br>
* It's got most of the pieces you need.<br>
<br>
* There is no really good framework that puts them all together in a<br>
decent way to get started. Chicago Boss was a valiant attempt at<br>
this, but... it's got some warts.<br>
<br>
* As an example of the kind of thing you'll have to learn about and<br>
put together yourself, consider using a database: at a minimum, you're<br>
going to want to integrate something like fuse and poolboy to make it<br>
work at any kind of scale, and make it work robustly.<br>
<br>
* The bits and pieces I would use: cowboy web server, Postgres<br>
database with epgsql, erlydtl for templates, jiffy for json, poolboy,<br>
fuse, lager, recon, relx and a few other bits and pieces.<br>
<br>
* If putting all that together is not your thing, and you are more<br>
interested in getting something up and running as soon as possible,<br>
you might look at other languages. Elixir's Phoenix framework runs on<br>
the same VM as Erlang. Going further afield, you have all kinds of<br>
choices, which have their own advantages and disadvantages, depending<br>
on what you want to accomplish. I'm personally a fan of Ruby on Rails<br>
for how much stuff you can do by including various libraries. People<br>
have managed to build businesses on PHP, Node.js, Java, Python, Perl,<br>
Tcl and all kinds of other systems.<br>
<br>
* Don't buy a computer, rent a VPS via something like Linode, and run<br>
Linux (or maybe some BSD system if you feel adventurous).<br>
