I'll admit, I'm a rookie. I've spent a few months now learning and writing PHP...is my effort in vain? Should I ditch PHP and dive into Ruby with a Rails framework?
I don't think your effort's in vain. If you like it, keep at it. When you feel confident in your knowledge on the language, you can then choose to move on and experiment with other things. Same for any language, really.
Myself, I'm just now getting started into Ruby on Rails. I finally figured out a project to get me interested in learning the Rails part of it. I just need to get cracking.
I like the idea of giving back...if you write a blog you give back. However, if someone doesn't think they will be able to add value with what they would give back, don't do it. There are so many sources of information out there that it actually does get tough to weed out the bad stuff. If you think you can produce good content, write a blog, if not, don't. Very simple.
