Actually twitter is fine on a mobile browser provided you use an account.
What I miss is the multi-container extension on fennec/firefox mobile. I keep using those sites in incognito mode but that mean I can only use one at a time.
Within 3 days of registering a new account they will prompt you 'for a phone number, because we detected security issues with your usage'. Don't know how having a phone number helps with security issues like that, but again -user hostile-.
I'm not creating a Twitter account just to read their public site, because they are user hostile and privacy invasive.
