Hi @fitinfun,
It's very good that You've already voted for 6 witnesses and only been here for a short time. You shouldn't feel to worried about it, but it's good that you are concerned about the topic.
Witnesses are people that run software that makes the blockchain, the public ledger that contains all the information and actions done on Steemit, on servers across the world. The witness list consists of around ~75 active people for the moment and all are doing their part to make sure the network stays stable.
There are 20 main witnesses, each generating one block every 3 second and one extra backup witness that generates the 21st block. This witness is selected based on voting and all backup witnesses takes turn to secure the network. If a main witness fails to generate blocks for one day, or they disable their server, a backup witness also goes in and helps with securing the network.
You can read much more about the topic in the #witness category if you are interested in how it all works.
Well, I will say this platform is very stable compared to some other places I use. I find a lot to like about Steemit as to interface, the clean site, and great social media sharing.
I really appreciate that explanation and I think it will hold me for now. I am up to my eyeballs in learning since I got here. It's fun, with good people, and I feel hope I will have a good place to get my message out. I'm trying to support what I can and not worry about what I don't understand.
I vote for people who ask for votes and seem like they want to do the job. So that is how many I have run into in about 7 weeks. I'm grateful you are all keeping it going. My technical skills are few :)
