I noticed the other day when I posted video clips to Vimeo, if I used more descriptive (longer) titles, then more people re-tweeted my videos. This behaviour has encouraged me to be more descriptive in my titles.
For example, rather than “Enabling Lock Rotation”, I am now using “Preventing your iPad screen from rotating”. The old title was very “feature” specific – in that it was labelled based upon the name of the feature. The new title is more behaviour or user specific – in that it describes how the feature is actually used.
