Technology blog is a website where there can be more than one author who put forth their ideas and then users can read and comment on them.

Technological blogs are usually the main source where launches are announced to the public, not by the company owners but by the blog authors. Usually the companies give out a press release which is read by the blog authors and hence they give their opinions about the product and date of launch.

Though these type of blogs are not places where you'll get support, some places do give out some important information about the good things and the bad things about a product, in technical terms they are called as Pros and Cons.
