These posts got me excited for this or that Rust creation:
Why I'm building a new async runtime (early 2020)
Announcement of smol, an async runtime. Made me want to finally make use of async.
warp (mid 2018)
Announcement of warp, a web framework. Made me seriously wanna dabble with Rust web landscape. The design looked novel. Last I remember being any excited by a web framework was years before, with the Pyramid, back in my Python days.
