doing making a nitter feed for non retweet Chen Weihua posts as an example (you can use any nitter instance, but some of them don’t support rss / it’s broken)

start with

  • https://nitter.ca/search/rss?q=

then add

  • -filter:replies+from:chenweihua

then add

  • +-RT

all together

  • https://nitter.ca/search/rss?q=-filter:replies+from:chenweihua+-RT

You can then subscribe to this nitter rss feed in your rss reader, all of this syntax is similar to if you were doing an advanced search on twitter itself and the syntax can be found in twitter repositories, you could do other things like only get retweets, only get tweets with links, only get tweets with images, only get tweets with a certain amount of likes, etc.
