Ok, new to Twitter . Kinda liked it, followed some good techies , but i am quite confused in using it.. can someone help?
1) how to edit your tweet? Like if you did a typo or just need to change some text
2)when i visit it after a few hours( say 4 ) it shows 'incase you missed' , i press it and it will take me somwhere down. What's the meaning of that? All the messages above that message are of last 4 hours?Am i supposed to swipe up or down?
3) WHY THE FUCK AM I SEEING EXTREMELY STUPID 'PROMOTED' TWEETS HAVING MY PM'S RANTING AND OTHER POLITICAL TALKS WHEN CLEARLY AM A DEV WHO HAS FOLLOWED THE GOOD, TECH PAGES? How to just unsee those?somebody please lend a good ML algorithm to this weirdly naïve site called Twitter .
4)any good tech pages to follow?(general tech related news or datasciences)

Thank-you

Wow that machine learning algorithms turn my brain in 🍜.
Someone have more simple course on that?
