If you think about it, there really isn't any conspiracy or anything. Anyone, looking to sell in these difficult times would absolutely make sure to advertise properly using the modern median. i.e. myhome or daft.
Unfortunately this is due to the recession down turn , the economy is not as it use to be during the boom years , and the property market has crashed very badly , that is why it takes a long time nowadays to sell a house .
daft & myhome are the main sites , but there is few others ,here's what i found after a quick google search , i hope this will help :
