The search and RSS feeds could certainly be better, I agree.

For search, the best thing to do now is do something like this:

https://duckduckgo.com/?q=site%3Aramble.pw%2Ff%2Fprivacy+signal+app&t=h_&ia=web

Search query: site:ramble.pw/f/privacy signal app and that'll search /f/privacy for posts/threads containing, 'signal app'. The site gets crawled on the other networks too, I believe you can do the same query with legwork.i2p as well.
