Poor quality identification questions and non-descriptive titles often go hand in hand. They have been an ongoing problem for the site. 

First of all, we should encourage users to *put reasonable effort into researching* the parts they're interested in. We can do this by making people more aware of part/set libraries (such as Bricklink, Peeron and Brickset) as well as part/piece numbers that can be found hidden in most bricks.

Last year, I asked for [support to have a 'how-to-ask' tips for identification tags][1], we had support for the idea and I had contacted a Stack Exchange Community Manager to get the featured added. I'm still hoping to hear from him and I've sent a reminder via SE chat to see if it can be implemented.
