there is a bridge, but some parts of the fediverse got very mad about it

Problem is that the whole concept of advertising is “telling other people what to do”.

• People use Google.
• Google tells people to use Chrome
• Chrome becomes most popular browser
• Chrome removes the " this site has RSS" icon from URL bar
• People forget that RSS is a thing
• People now rely on Google News and other biased sites to get information
• biased sites tell people what to do

RSS is freedom
go tell other people to use it
also Lemmy RSS community

Your post is missing the most important information that you wanted to share

GotHub seems to display basic GitHub stuff decently well.
https://gh.whateveritworks.org/

so this is similar to LibRedirect?
https://github.com/libredirect/browser_extension
https://libredirect.github.io/
check out this list of privacy frontends and see if you can implement any of them in Predirect

Also, I see that you only handle one instance for redirect. Either the default instance or custom instance.
Consider implementing multiple instances. Here is list of instances that LibRedirect uses:
https://raw.githubusercontent.com/libredirect/instances/main/data.json
Here is a list of instances that Farside.link uses:
https://raw.githubusercontent.com/benbusby/farside/master/services-full.json

Both LibRedirect and Farside still have to deal with the rate-limiting problem with Youtube and Reddit and I assume other sites as well. Invidious instance or Teddit instance can be rate-limited, resulting in video not playing or post not showing up.
If your extension does not distribute user traffic across multiple instances, then I assume that your chosen instances will get hammered into ratelimit even faster than other instances.
So consider thinking about solution for this.
One of suggestions that I like is to allow user to provide an URL to a list of instances.
That way, someone or some automated system can periodically compose a list of instances and users can “subscribe” to that list.

Also some useful links:

gotta fail fast

link is borked 🙁

I think that starting from the beginning on Lemmy is a great opportunity to make news communities make more sense.
Specifically, !worldnews should not exist. It is a relic from Reddit that implies that !news is not for all news but just for news from some part of the world. In my opinion, there should be effort put into making this community as inactive as possible. As that would be the result of people posting news from all over the world in !news.

lol this reminds me of psDoom
