I've been on Hive for about 3 weeks now. I started playing Splinterlands about half a week before I found the rest of the community and started exploring it. My first post was on PeakD about 21 days ago and since then I have learned a lot, found a lot of great content, and one particularly great community amongst all of the great ones on Hive.
Let me preface this by saying, most of this section is guaranteed to be old news to you. But for the new cats on the block maybe you'll see this and be able to find something new faster than I did, if not it's at least a good way to reflect.
One of the earlier things I learned is it's incredibly easy to spread yourself to thin by getting into to many tribes and tokens to early. As someone who doesn't have a lot of money available to be able to put into investments the only purchase I've made from putting outside money into Hive was the $10 spellbook for Splinterlands. To this day I have only made a couple of very small purchases due to not having available liquidity to sell and no money to put in. Early on this made making regular posts, comments, and interactions in the many tribes of Hive difficult due to a lack of RC. Having limited posting and interaction capability made it more difficult to become a part of the community and to earn the tokens necessary to do so. That being said 3 weeks later, while I still don't have an abundance of tribe tokens for voting power or excessive HP, I have plenty of HP to be able to post and interact regularly and am have enough tokens staked for some of the tribes I interact with regularly to at least help push posts over the dust thresh hold. I didn't get here all by myself though, the HP that has helped me for the past week while to help me be able to maintain the posting and interactions that I have been in order to start becoming more of a member of the community and to more easily earn my own came from someone else, this leads me into the second thing I learned after coming to Hive.
Make Friends! I can't stress this enough. If you can't become super involved on the Hive engine itself due to lack of RC join the discords for the tribes your in. Every tribe, game, and front end that I have looked for a discord for has one. I haven't looked for a discord for all of them but most, if not all, have one. This is a good way to become a part of the community of these tribes and make friends and acquaintances. Doing this helps in many ways such as having more experienced people to answer your questions (and if you're like me you will have many), helping you to find new things on Hive and off Hive that you may not even know to ask about, potentially finding people who may be interested in the content you post helping with upvotes early on, and if you're lucky like me maybe even people who will help you with delegations to help roll you're snowball down the hill a little faster. Please keep in mind that this is my personal experience and none of this is guaranteed. Shout out to 
Something else I learned is if you find yourself lacking time, like I do, and have the resource credits to back it up you should look into curation trails. Hive.vote makes it easy to follow curation trails and managing the settings for the ones you follow. Following curation trails that upvote content you enjoy and would upvote anyway is a good way to help good content get curated, and to enjoy some passive curation rewards yourself.
Lastly, pictures! I was advised, and have since found it to be true, that putting images in your posts can help to increase your average reading rate. This in turn can help increase your average interactions from readers, upvotes and comments, potentially leading to your content getting to more people and in turn potentially more of hat ever craved Hive.
There are some great places to find great content, depending on what you're looking for. I use Peakd as my main interface for content on Hive, however if I am looking for specific content I branch out a little. Right now if I'm not on Peakd, I'm usually on Splintertalk, SportsTalkSocial, Stemgeeks, or LeoFinance. If you haven't yet I would recommend checking them out.
My favorite community and Tribe on Hive by far to this point is the $PIZZA tribe. Obviously their token is the PIZZA token. Their discord is full of great people and is where I ran into
