But yeah if you use a hive as a first tag, or even just a name of a community as a first tag, or post directly through a community's front end, your post will not appear on your own steem blog. It WILL appear under "all posts" on  your page though
I think this is bass ackwards. The reasoning is that some posts one might be for the community's eyes only, but I'll bet there will be fewer posts like that, so essentially most of us will have to go back to the community and "resteem" (called *add to your blog* or something), making even more niggling work that we need to do to publish a post. I do not like this aspect so far even on tiny bit. It's not horrible that I no longer get a notification for every single tiny .1% upvote, but the cut-off of .02 for notifications has once again only harmed the little guys. So if one of us with a .03 upvote upvotes a brand new or very low paying post so that our vote is under .02, the blogger will NOT get a notification. That means every upvote I cast on any post. I feel screwed again. Now if they made it so that no upvotes less than, say, 5% generate a notification, I could deal with that. But as it is, we little guys just disappeared a bit more on the blockchain. 
I freaking HATE that I have to go to "other" then "notifications" to turn off the red light for notifications i have already seen. And I can't get to my own blog without at least two keystrokes. BLECH.
