a good article i read for anyone who is a programmer

I read this article here and I think it contains some useful information for anyone who is a programmer but cant think of something to work on. I find myself in this same type of predicament where i want to program something but want it to be used by alot of people. Asking for advice for this online isn't necessarily a bad thing but would it really solve the problem or is it just generally a waste of time? For beginners it definitely is good to focus more on a project that interests you and not worry about how many people are going to use it , experience is key and it is better to gain good experience on a start up project that you like than worrying about attracting a large audience.
