You'd think they would have figured out targeted ads by now. If I follow people who post about RF/Microwave, antennas, SDR, and ham radio, one would think I'd see ads from Keysight and Tektronix, but no, it's garbage like football and pop music. FAIL! I also don't like that I don't see all the tweets from a person. They are pruning the timeline. Good riddance to twitter.
They are leaving an enormous amount of money on the table by not inserting their own affiliate links though.
