I'm trying it now and getting more used to the reason for hashtags. It is different but that's what should make it more secure and less mean.

@rainmanjr As you can tell, I like mean.

@barjoe I've noticed. It has its moments.

@rainmanjr I don't understand how it works.

@barjoe Choose a Server/Host (called an "instance" ) who's theme is good for you and then use #'s to find specific topics.

@rainmanjr Yeah but how do I search for people to follow and how do I know what "instance" they're in?

@barjoe The hashtags allow you to see the post across instances. Click on an interesting hashtag and begin following people who you like within it. You will do the same with other hashtags and people who follow you so no problem getting populated.
