Monica Hesse's article in the Washington Post about "Click Through Activism" focuses on the ways that many social networkers join activist groups without the intention of further supporting the cause. Some of the reasons for joining could be guilt or simply fallowing friends. Few of the people joining truly support the cause. Sometimes people do not even know anything about the group that they are joining. An example of this is the "No to Demolition of Stork Fountain" group, which was fictitiously created for the purposes of a psychological study, yet reached over 27,000 members.
When it comes down to it the numbers that join these causes show a public outcry and support, but do little else. It is easy to join a cause on Facebook, however it takes more of an effort to fallow through and act on that issue. Because of this many of these causes loose support and fail fairly quickly. Instead of this "click-through activism," taking a more proactive approach is the best way to give support to a cause you believe in.
