Mike, you should decide why, or whether, you want to be here.
WikiTree is free. That's a great attraction for some people. I joined because I wanted a place to display my research to my relatives who were moderately interested in our family history, but not enough to pay for a subscription to a genealogy website.
There is a community you can draw on for help.
The one-tree structure is attractive to some, but others would prefer to have their own tree (usually on a paid site).
WikiTree links DNA test information to ancestors so that other descendants/researchers can explore the genetic connections.
There is a learning curve. Many of us have learned to deal with WT's structure and requirements fairly well.
The big downside (or one of them), I think, is that WT is not a records repository, so you will have to get your sources elsewhere. The process for posting sources here is a bit more laborious than on Ancestry, for example, but there are some free apps and extensions that can make that easier.
If you decide the benefits are worth the effort, then I suggest starting with the Greeter messages on your profile, which should provide some links to help pages.
