I imagine in the coming months (years?) we will see Google transition away from Google+ as a catchall platform, and back to standalone solutions similar to their offerings from the pre-Google+ days. A bit off-topic: I think it's the right move for them. Google+ was (and still is) a pretty cool platform. It has a lot of neat features that existing social networks lack. Facebook just somehow holds on to their userbase…
What are some of the parts of G+ that you particularly like?
Hangouts is great. Remember that Hangouts launched as a part of Google+ before breaking out.
Ironically, Google+ Photos is also one of my favorites. If you snapped photos on a vacation, you may return to find that Google has stitched them together into a "story" -- including where you were when you took photos, who you were with, etc. It's a nice way to relive the memory.
Circles is also a very simple concept for social network security. It's easy to understand, and I like that Google left it out in the open as something you should definitely do. Facebook has a similar feature, but it's not in their best interest to highlight it.
