Front end chops
The role of the front-end web developer has become more important, more complicated yet simpler in many ways.
The role of the front-end developer has become more complicated with the tooling and experience we are expected to have under our belts, it's also become easier in a lot of ways though.
Tools have complicated things though, there is now an ever present learning curve before us. If you join a new team or project you will probably be expected to learn a handful of unfamiliar tools that the team has adopted, you'd also do well to be able to offer a handful of your own practices/tools/frameworks that you like. Tooling is really highly valued at the moment.
I'm a keen learner but a late adopter, I don't jump from one hot thing to the next. If you always adopt the hot new thing, you will often be adopting more code and complexity, the key is to find tools that require less code and complexity and allow you to do more.
Browsers are great now, IE is dying. Web standards have won and it's now easier to develop for the web. CSS3 means that there's a lot of power and visual reward for a small amount of effort / code. While there's more to learn, a lot of libraries allow you to go further and do more.
The best tools save you time and allow you to write better, more elegant and maintainable code.
