You should, working with SVG is interesting. It makes you think differently in how to handle UI design. I wish it were better supported across the board in browsers, it would help solve a great deal of UI issues.
It really kind of depends on what you want to do with the SVGs. They can cover topics such as icons, animations, UI, charts, reports, and so on. Just about anything you can imagine using a vector image instead of a raster applies. Many javascript libraries already exist to cover many of the usual situations. You can look into those and play with them to figure out where your interests lie.
And this isn't limited to web technologies and browsers.
I started learning SVG going through all the jenkov examples - really great resource. The SVGs I create now are designed to be easy to understand because I wanted to pay it forward. Have a pick through my other pens and maybe my channel http://YouTube.com/+framespark
