Hello @cabracho and welcome to ecency / Hive!
Not sure how you discovered this blockchain? Anyway, I'll try to help you out a bit.
Try to write a rather long article to introduce yourself. My tip would be to search for the ocd community and use the hashtag #introduceyourself.
Besides that introduction post, it's a great idea to look for 1 or 2 (to start with) communities which have a subject in line with your interests. It will be much easier to connect there.
Finally a rather practical advice, don't try to copy your same article in different communities. Instead you can reblog it to different communities, although people favor authentic content over reading the same post in different communities ;)
Good luck on your Hive journey! Feel free to ask questions!
