Nevertheless, the fact is only topic title is not enough to get merits, because it is not enough to make quality, constructive, useful topic. The general quality of each topic depends on its internal contents by several following components:
1. Does the topic has relevant questions? (that means is the topic neccessary to start a new topic, is it not been answered wherever before)
2. Was the topic written in well-formated style? (don't use capitalizations, hightlights, underlined, oversized-images when not needed)
3. Was the topic written with proficient English (with little inapproriate vocabulary usages and grammar errors)?
Might be more important components, I am not sure; but in my view, those three are the most important ones which can help topics to get merits.
