1) Changing Circles to People and presenting me "You might know" folks e.g. from companies I worked for more than a decade ago. Could you imagine seeing several hundreds of "suggested people" who were app. 15 the time I worked for a company which had more than 40,000 employees at that time?
2) Discontinuing Google Reader
3) Discontinuing the CalDAV-API, which means bye bye syncronising my local calendar with gCal
4) That monster size picture on the profile page with the microscopic punch-hole for the profile pic.
5) Seeing randomly at least one service per day not working as expected because of "new exoting improvements"
6) Turning Picassa into a useless piece of crap
7) Events and Hangouts became not longer searchable
should I continue?
