Every now and then, a new internet start-up comes along that fits snugly in a gap between two other types of website. In this case, BlogZa appears to fit in between a regular blog and Twitter. The former allows you to blog at length about all manner of different topics, whereas Twitter has a strict 140-character limit.
However, BlogZa limits you to a single sentence when you sign up for one of their blogs, so it may suit some people more than others. It is very new at the moment and there is no indication of how many people may have signed up for the service. The very simple home page has a short description of what the site is about, followed by a short registration form. This requires you to fill in your name and choose a username and a password. You also have to fill in your email address, but that is all the information you need to give.
BlogZa could well be good for individuals to use as a blogging platform. Nevertheless, it is also very likely to be used by people who want to promote another site they may own. There is no indication of whether links are allowed in the sentence, so it remains to be seen how the site develops as more and more people join it. It may well appeal to those who like brevity in their blogs, so it is worth keeping up with for that reason alone
