A good way to target your domain to a specific audience is to do some keyword analysis on the keyword "post advice".
If you use
Market Samurai you can work out what people expect to find when searching for "post advice". Then you might be able to target the site better to an audience thus working out what to put on it.
Another thing, don't have your site under construction. Throw a copy of WordPress on the domain and write 300 - 500 words on a subject closely related to what the site might be about. This will help you in the long run.
