Yeah for sure! I think it'll be a little trickier now that more people are looking at old questions, but there's definitely more out there.
The main way I find questions are through the tags, the questions of which I go through chronologically. Answers from the early years are way more likely to have outdated (or generally poor) answers, for example. Here's one I did recently:

If you have a lot of knowledge in one department, like a specific game, try to focus questions with non-detailed answers on that topic. For example, I am probably the most knowledgeable person about Black 2 and White 2 on this site; I answer a lot of questions e.g.
https://pokemondb.net/pokebase/124550 ,
https://pokemondb.net/pokebase/43074 , and
https://pokemondb.net/pokebase/106291 .
Other departments like competitive information and game design hypotheses just come with time and experience. Good resources include Bulbapedia and Smogon, as I'm sure you know. I don't know everything about Pokemon, but I sure know how to look up a Bulbapedia page!
It can be a lot of work to 1. source old questions with bad answers and 2. answer them adequately yourself. It takes a lot of time, but you'll start getting a feel for it the more you do it. Try to remember what you've written about, in case anything changes in the future (e.g. I recently had to go back and edit an answer I wrote 5 years ago about how many Mega Evolutions there are). Good luck!
P.s. I read what Silver and HT wrote earlier. You're a great user and I love seeing people still take an interest in the DB. You're doing well. :)
