As in the case of Picasa Web, Reader users who posted and shared content using a pseudonym must now do so using their real Google+ name. Google has said it will allow for the use of pseudonyms in Google+ but hasn't said when nor how.
The Reader changes and its integration with Google+ have led disgruntled users to complain in discussion forums, Twitter posts and blogs. These users even set up an online petition asking Google to reconsider and give them the option to continue using Reader's native sharing features.
Beyond the requirement to use their real names -- a major concern specifically for users in Iran, where many of the complaints have come from -- these users also dislike losing a dedicated space for RSS feed sharing. Shared Reader content will now be lumped in with all the other types of things people can share on Google+.
Sharing Reader content will now be based on Google's +1 button, which is tightly integrated with Google+, and on Google+ Circles, the feature that lets users organize their Google+ contacts into different groups, like family, co-workers and any other category they define.
Another inconvenience for these users is that they will have to recreate the groups of Reader contacts with which they shared. Those groups that existed within Reader will now have to be compiled again within Google+.
