Well let me say welcome to the community! A great place to learn about how the layout works is Hubski.com Primer page. This may help you with the format also thesummerking. It may take a little to get use to but it is very nice and easy once you get the hang of it.

As for finding tags and people to follow, when you open an article you find interesting there is an option to click.

It may be, follow #books if the person posted it in the books tag. To follow people open their post and next to their tags it should have, follow username. By clicking those it's added to your feed and things the users share or post and the tags you follow show up there.

To see all the post (I believe) click on global at the top of the screen. You can either sort by time or what I personally call points. The little circles surrounding the big circle. The more points the more your article has been shared (guessing again).

You can also click time and posts will be in order from newest posted to oldest. thenewgreen I'd like to double check, is this correct or is it all done differently?
