Too Much "Stuff" is Sent

I found an article written by Nicolas called "'Limiting Sending Rights' as Solution to Information Overload," where the writer is arguing that maybe it is the "sender" that is causing us to be overloaded with information. The writer goes on to talk about how there should be new methods put in place to limit amounts of information that can be sent to subscribers and so forth. 
The writer states that "once the connection between sender and receiver is established (e.g. subscription to a newsletter) the sender can send us as much information as he or she wants." He backs of this statement by saying that once the subscriber is in "connection" with the writer, the subscriber has no control over how much or what information is sent to him or her. The warrant is that every time someone subscribes to something, they will be bombarded with useless information and eventually unsubscribe out of annoyance.  
I think that sometimes this can be true and sometime it can be false. Many of times I have subscribed to a new letter or website and have only gotten useful information. For example, I belong to a nutrition group and get paper or things happening dietary in our world. This group only sends me things that are relevant to my area of study which is didactics and help me be aware of current problems. However, I have subscribed to things that eventually I unsubscribe to just do to the fact of the information overload 
occurrence as discussed above.
The paper goes on to discuss numerous ways that this overload of information merely from the sender could be filtered or stopped as a whole. There is definitely more than just the sender to blame though for this overflow of information. We as americans need to really stop and think about what information we are reading and subscribing to on a daily basis.
