Let me begin this post by saying, these are the platforms that work for me. Everyone will have an opinion. All are valid. This post is how I decided where to put my energy (for now).
1. Twitter. Yes, we have some changes at top, and those might cause me to leave at one point. Not yet. The writing community has built strong bonds. There are many great folks who share amazing and useful tips about the publishing industry. If you stay, be sure to follow: Jeni Chappelle, Victoria Strauss, One Stop for Writers.
2. Instagram. I use this platform to promote my 'brand' and introduce myself as a person to readers and the writing community. I follow my favorite authors to learn more about them and books coming out. It isn't the best for interaction--certainly not the robust kind you get on Twitter--but it is a mostly positive place. If you are there, be sure to follow: your favorite authors, publishers, and bakers (lol, or is that just me?).
3. Mastodon. This is new for me. I just joined a writers exchange, and so far, everyone is lovely. Don't be intimidated by the push to CHOOSE YOUR SERVER. Search for 'writing community' or another term or phrase. Honestly, from what I understand, the server you join will not limit your interaction. If you do join, find me!
I would love to hear where you find your people online. Let's connect, share resources, and support each other!
