I'm also thinking of streaming now, it looks fun
At the moment I'm just following people and seeing how everyone approaches it. I'm also not sure how to talk continuously about nothing particular, so I'm thinking of starting by streaming games while I get the hang of it, and figure out things like: what is discourse, whats with all the flying graphics everywhere, and why is there several minutes lag on comments going through?
Twitch only ever seems to list one or two streams running for stitching or crochet (I go through the communities pages), is there something I'm missing or is it really this quiet?
Talking to yourself for hours is definitely a learned trait. xD And yeah, much easier to talk about what's going on in an action-paced game than over a slow stitching process. Once you've a few regular viewers, they're usually more than happy to converse about pretty much anything, and you can feed off that. How was their day, the last movie they saw, their preference of pie vs cake, etc.
The 'lag' depends on internet connection and location. Usually only a few seconds, but can get fairly lengthy if you've spotty net. And is something you grow used to as well. And the flying graphics are different each stream, but usually a way to encourage interaction. If you use an emote in chat, it may pop up on screen, for example. Or if you follow, an alert will pop up encouraging the streamer to thank you for following them and allows them to start a conversation with you. etc.
As far as the listings - Twitch recently released 'Communities' rather than the hashtag system they had before.
BEFORE, you could put #Crochet in your title and you'd show up. Now you have to choose the Crochet community to be listed under crochet.
Which sounds all well and good, but it's so far down on the list of communities that streamers are not likely to be found by new people who don't know what crochet is, for example. So they list themselves under 'Relaxation' or 'Positivity' or any number of generic communities that are easier to be found. Unfortunately, that means if you're looking for crochet, it's even harder to be found.
Because yes, there are 80-ish streamers who stream CrossStitch. But sometimes they play games, or knit too. And they're all on different schedules. So maybe we only have 1-3 streams on at any given time.
You can try browsing Creative as a whole:https://www.twitch.tv/directory/game/Creative
Or check teams designed around the crafts of your choice.
KBN, for example lists all sorts of fiber-craft artists:https://www.twitch.tv/team/knottybynature
Pixel Stitch is more Cross-Stitch specific, but only those who stream semi-regularly are listed*.
(Or at least, they did at the time they were added to the team.)https://www.twitch.tv/team/stitch
Or you might check the TwitchStitch twitter for 'going live' or schedule tweets from streamers known to crossstitch:https://twitter.com/sirithre/lists/twitchstitch
....aaaand this is what I mean about needing to get to know the community first and how the site works. xD It can seem overwhelming at first, but that's why most people tend to watch a few specific streams regularly, who stream on a set schedule. Once you've found some streams you like.
tl;dr - EXPLORE.
