Well it may not be easy to define a proper title. This includes those who don't know anything about defining main ideals, purpose of a topic, identifying a conclusion, etc.
It's all about "reading comprehension."
However, if a topic is pretty simple, and if a newbie shows his/her first model to the community, for example, like a high-definition TV, then a topic starter can be a little more specific other than "my first model." What they can mention in the subject is "my first model: HDTV" or "My HDTV model -- have a look."
I hope you get my ideal.
