quick note about tags:

Tags is a list. But each tag is also a list.

In the list the represents a given tag it has a tag identifier as the first item. Like "p" (which means pubkey). After the identifier is arbitrary amounts of information as strings.

For example if you tag someone in your note. In the event data would be a tag that likes something like this:

["p", "06a533dahdahdahmoretext"]
