We often hear members saying 'why do i have to see posts from xxx forum?, I'm not interested in that at all'

There is an answer.

It is easy to exclude forums from your view, so that posts from that forum, and their relevant subforums, do not appear in the new/latest posts section. You can effectively remove any unwanted forum.

To customize your view and remove forums, go to edit options and, at the bottom of the page, you can select the forums for removal.

To select multiple forums, press and hold CTRL key while clicking on the forum titles. To clear exclusion, select "Reset Exclusion" without holding CTRL key.
