Give it some time, explore around.
You may find that it is actually EASIER to get to content that you are looking for, provided you have a name or a term that describes what you are looking for.
For example let me put out a couple of words.
#Destiny
#Forumrules
#Gaming
#halo3
Now, try double-clicking on any of those words. Go on, I'll still be here.
That alone should give you an idea and a little insight into how things can now be found here. With a logical tag (or tags) someone will be able to days later, or months later, find that discussion and start it back up. Check your settings to make sure that you get notified when someone replies to you, and you'll get ongoing conversations about things that YOU care about.
It's new, it's different (especially compared to how it used to be), but it has a lot of power and a lot of promise. And soon, really soon, there are going to be a LOT of people here all asking new (and old) questions. These tools should help everyone out.
