I'm new to the area as well and have found the Pittsburgh N'at list on Bluesky to be great. I'd share the link but it isn't shareble. Have to search and go into Lists (or similarly named.)

For local news, @triblive.bsky.social and @pghcitypaper.com. (FYI, don't follow or post anything by the Post-Gazette or its scab writers - they are despised here b/c despite NLRB Orders, the PG owners have refused to bargain in good faith w/ staff who have been on strike since Oct. 2022.)
