I have favourited some tags. I see on homepage related questions getting updated regularly. But out of those questions I can find few questions that I can answer and add value. What is bad is most of those questions have already been answered or have vague answer such that I can't really figure out if that answer is what user wanted or not. Sometimes that is what user wants and I avoid adding another answer. On other questions I feel why should I spend some effort when someone else might be already composing an answer to the question.
Check out the Unanswered tab in some of your favorite tags. Some of the more popular tags have thousands of questions that don't have any answer at all, and even more that have a few answers that didn't receive any upvotes. Also, the Unanswered tab is sorted by votes, so the questions at the top should be high enough quality that they'd be worth a look.
These are personal favorites of mine.
Use other sites and then you can focus on your combined profile flair.
Provide more details than others.
Use style formatting - not just bold and underline but other styles and ue styles more than others to get noted- use ###'s for various level headings, use "---" for line dividers, etc. Include images such as screen shots (partials work best for zoming reasons) to get attention.
Tag your questions well, tag your answers well. If you get accepted and the question has tags missing, add them.
Ask questions! If you're having issues getting the right answer 'in', ask good questions - they get points too!
