Indeed, my local government of Troy, Ohio (~25k population) offers RSS feeds with useful info about things like holiday closures, road construction, christmass tree pickup, etc. https://www.troyohio.gov/RSSFeed.aspx?ModID=1&CID=All-newsfl... There's also a calendar feed with city council meetings and such.
(Hello Troy (and Overfield) neighbor... >smile<)
CivicPlus, the hosting company for Troy's site, does a fairly decent job. (They're rather pricey, in my opinion, though.)
Miami County government uses them to host some of the various County websites. We expose some RSS feeds, send email notifications, etc. The biggest problem with the platform is getting elected officials and departments to see the value in using the platform (versus just posting scanned PDFs, Excel files, and doing things "the old way"). The City has a little easier job because there aren't so many independent elected offices.
