Hello World! 
Yet another programmer is joining this awesome community. I'm looking forward many interesting discussions. #introductions
@cz35iek Welcome. I've been pleasantly surprised at the quality of the technical conversations I've had on the #Fediverse. Not everyone's even into tech--which is good!--but there are some really smart people who like discussing things.
@byron thx for onboarding hints :-). I'm still familiarize myself with this platform. For sure I won't hesitate to take a look a #fediverse. Probably there is a way to observe hashtags?
@cz35iek But to be clear when I say Fediverse I mean the whole shebang, not just the hashtag -- all the Mastodon, Pleroma and dozens of other platforms that connect together. That's part of the fun, that you can be on a Mastodon server and follow people who aren't just on different Mastodon servers, but also using GNU Social, Pleroma and various other types of servers on the Fediverse network.
@byron I've got this second thought after asking my question. It looks like sometimes it's good to ask even those silly ones. :-) Now I need to look into how these protocols works / interoperates. Thx again.
@cz35iek Depending on what app or interface you're using, you can usually search for them, and some will also let you either save or follow a hashtag, but that's client-dependent.
I think most clients let you click/tap on a hashtag and view it as a search, too.
