I have recently joined stackoverflow. Mostly, I am doing a good search on my programming questions here and can find answers on my own. Yet this approach does not help with my Stackoverflow reputation, and it seems almost all the basic/intermediate level questions I can come up with have been previously asked. I also see many questions flagged as previously asked, answered etc. So what would be your advice to build up a reputation on stackoverflow for a newcomer to this site? It seems right now I can only ask questions, not even answer. :-)
If you're getting answers to your questions, stack-overflow is fulfilling it's purpose. Do not worry about reputation points.
However, if you would like to get easy rep points....
1) Go to stackoverflow.com and sort questions by date.
2) Only look at questions which are <30 seconds old and are of low quality (most of these questions will be duplicates)
3) You can either answer yourself or quickly do some research to find the answer (as I mentioned most of these questions already have answers on this very site)
4) As quickly as possible, answer the question. Bonus points if you flag the question afterward with the related duplicate/reason as it helps towards the
Marshal gold badge (and maybe other badges)
