The increasing popularity of blogging has led to a proliferation of blog hosts on the web, with free blogging sites being especially popular with those who wish to have a platform to express their views to the world.
The top reason that bloggers choose to go with the larger free blogging sites is simple: reliability. By opting for a well known company to host your blog, you have the assurance that your blog will have solid uptime and will not disappear on you overnight.
Companies which are well established tend to have a lot of resources and be able to easily handle technical problems. That said, a lot of bloggers are not swayed by this factor alone.
However, there are quite a few bloggers who instead choose to go with smaller blog hosts, largely out of a desire to cast their lot with the underdog rather than the industry giants.
After all, on the web even the smallest company can become a household name around the globe, as long as thy provide a high level of customer service.
