I'm not sure how new you are, but I started over this past weekend with both kbin and sh.itjust.works. Having a few uninterrupted hours checking out the different tabs, communities, magazines, etc. was a big help. I basically jumped in also, but just having time to LOOK at things, read posts, and check out different communities made me feel comfortable. I still don't grasp how the microblog section works, but that's something new to explore next weekend I guess.
