Wordpress Multisite vs No of blogs ?

Hi I m new to BHW. I m planning to create some blogs using Wordpress Multisite ..how many blogs can I make with it..can I create unlimited no of blogs ????

Technically, yes you can use multisite to just make more and more blogs. Having your website in a multisite function will allow you greater flexibility for each individual blog, but if you plan on tending to them and monitoring them all at once, it becomes difficult once you reach higher numbers.

If you'd like to generate something of an "authority" site, I believe you should stick with "yoursiteurl"."c-o-m"/"subdirectory", as it's much easier to manage and ensure you're website has a common theme and template. However, if you do prefer the "subdomain"."yoursiteurl"."c-o-m", then it will allow greater flexibility, but it's going to be a chore if you want to be sure to interlink all of them without some sort of template cloner to help minimize the work.
