Can Twitter Overcome Advertising Glitches?

Twitter (TWTR) recently reported problems with data processing that impacted users of their advertising platform. Equity Research Analyst, Michael Pachter called this mistake unforgivable and said the company will have difficulty increasing ad revenue moving forward.

He also commented on Amazon (AMZN) facing margin compression from similar retailers. He believes Amazon has the scale to overcome competition, and smaller retailers will end up being squeezed out.
