While the OpenZeppelin Forum is one of the best places to discuss subjects concerned with Smart Contract security, it's also a great community to join if you're interested in Ethereum and dApp development in general.
You might want to start by browsing through the "General" subforum which covers different topics such as "Guides and Tutorials", "Project", "Showcase", etc.
Protip: Search for the "coding-journey" tag to read how fellow dApp developers navigated the Blockchain space and got started with Smart Contract development.
