I am currently building my first 2 websites using Craft, and so far I love it (with very limited knowledge of PHP)

When researching about making the switch, I ran into a few articles I found very helpful. Here's a couple: http://taechogroup.com/blog/10-reasons-why-we-love-craft-cms

If you're familiar with ExpressionEngine, Craft will come naturally. Whole lot of EE devs abandoning en masse since development stalled for so long... Craft is like what EE would be if it were a) made in 2014 by b) an actual developer, instead of a rock musician. Twig takes a little getting used to but that's mainly because it's so powerful.

My team is already on its 3rd Craft project and another local company is making the switch. It's basically the best thing ever.

I'm using it for http://www.31three.com and really enjoy it.

I haven't fully wrapped my head around the templating language (twig) but was able to wing it enough to get things done.

These docs are really handy if you're coming from and ExpressionEngine background.

I think if your building sites from the ground up and want to focus on creating something specific to the clients content & functionality needs Craft CMS is the way to go!

On the downside you don't get all the fancy built in stuff you can get from Wordpress or Joomla, the upside is your site will be streamlined as possible w/ no bloat.

For instance, there is no menu creation area in Craft CMS, you gotta build it yourself.

If you can wrap your head around PHP, Twig and are ok with reading the Craft Docs I'd say give it a whirl. You will get into trouble tho, so be prepared for some long nights of scouring their docs, just trying things, posting on the forum, etc and waiting or replies.

I'd suggest getting on the Craft G+ forum, I've had real good luck getting answers.

Also, one good thing to keep in mind is Craft is so flexible there are 100 ways to do 1 thing, it's really up to you on how you want to code it. You can also just run your static site on Craft, and then just integrate certain area's bit by bit.

For instance my first try at creating a Craft site was my portfolio: http://ryanbelisle.com

The whole site is static except for the Portfolio, Blog and Project grids.

My 2nd site developed was Corben Architecture: http://corben.com.au/

All in all I loved using Craft. But if your doing it for client projects I feel the site build is more on the expensive side because you really have to custom create everything instead of just installing Wordpress and everything is built in. Another upside is anyone that I've shown Craft too loves the simple interface.

Previously an EE based agency, we use Craft (almost exclusively) at Taecho Group (http://taechogroup.com/) and I've got nothing but good things to say about it. It powers our website along with about half a dozen other websites we've built for clients over the past year or so.

We also launched Craft Plus (https://craftpl.us/) a few months ago with a big focus on supporting the Craft plugin and resources community. Craft Plus currently has 6 commercial plugins with screencasts, tutorials and more plugins on the way.

I co-run the Craft Austin (Texas) meet up with the guys at Sputnik (http://sputnikcreative.com/). So I think it's safe to say that I love Craft.

Advice-wise learning Twig will take you a way and depending on your PHP background building plugins will allow you full access of the power of Craft.

I just moved my portfolio site from WordPress onto Craft and found the process pretty painless. Best of all it makes no assumptions about the site/content, and has great inbuilt support for custom fields/matrix repeaters etc out of the box. Even assets can have custom fields. Great community too.

I still think I'd prefer if it didn't use a templating language and stuck to PHP (like WP does) but Twig is very easy to pick up.

I use it for http://ibrewmyowncoffee.com and am really happy with it.

I use Craft CMS for all my projects. I love it. It's amazing.

I've been wanting to use it for a while, but $300 per install is a bit of a turnoff?

I think I'm building site number 5 or 6 with it. Coming from WordPress it's been the best experience.

I'm not a backend dev whatsoever and I haven't run into any problems building the marketing sites that I've built with it so far. I was pretty good at Twig before using Craft, but I've only gotten better in the 8 or 9 months that I've been using Craft.

Im using it on http://lovindublin.com. It was a bit tricky to migrate over to Craft from Wordpress but since then its been a breeze. Easy to learn, easy to extend, although it is missing a couple things that I'd like (native importing, field migrations & better tag support), but I love it.

Currently in the process of converting our third site to it.

It lets content be treated as such and not fit into a single blogging platform like Wordpress. It also has 3 great developers working on it and they push updates constantly & are really helpful.

Their docs are useful but I tend to visit their stackexchange site daily (http://craftcms.stackexchange.com/) to keep learning more about it

I used it for http://seachant.co and have really enjoyed it. I come from a long history of ExpressionEngine work and Craft isa breath of fresh air.

I've built a couple sites with it, including my own site, and I love it. Twig takes some getting used to and the documentation could be better (they're working on it) but there's an excellent community of developers on Stack Exchange that can help if you're stuck.

I've been working in Craft since it launched after years of ExpressionEngine. It really is as fantastic and powerful as it seems. The Craft team is super responsive both in support and updates, and the community is awesome. It's become my default CMS.

I highly recommend purchasing these Craft CMS Summit videos. Anthony Colangelo's talk is worth the price of admission alone:

By the way, this is Craft — just in case you haven't heard of it before.
