Chas Begley: An interesting post by Nisha Kaushal on the limitations of Twitter for marketing which while I don't agree with all the reasoning makes a number of valid points.
The five limitations the post highlights are:
1. A Lack of Community
2. Zero Monetization
3. The Lack of Multimedia
4. Maintaining Their Identity
5. Public Image
The flip side to Twitter's lack of personal community is the fact that it has enormous reach capability and can spread a message faster than any other network.
The other big advantage of Twitter is that it gives you access to major influencers, you can contact anyone on the network and while they may not necessarily respond you can still get you message to them. This ability to extend reach to those influencers is simply not available elsewhere.
