Yes. I do not mean to imply it's an insignificant difference. Its insurmountable if all nostr is is a FOSS twitter clone, honestly. But I also think is looking at Nostr the wrong way. Twitter is like Television. Nostr is like the internet For years TV ran on the way it had and even though the internet had ways geeks could download TV shows and even some streaming here and there people still used their DVRs and cable etc. But over time the internet ATE all that. It was not just a better way to do TV, it was a paradigm shift. Nostr has this same potential in my humble opinion. The Twitter like clone is really just a single proof of work application. People are developing new things on it that never existed before. See #safebox as a good example.
