Opera is an Internet cooperation that offers free Web Mail and Blog. The Web Mail has Ads in it but its Blogs do not have any ADS in them. and what's more interesting is that the Web Mail is not connected to the Blog. so if you have an Opera Web Mail account it does not mean you can use that account to get a Blog. You sign up for a Blog differently. So how does Opera benefit or earn from its Blogging service since it offers free Web Space and Bandwidth?? is there any other way it can earn money from this other than ADS??
what is the search present in opera toolbar? Its google. Hence google is paying opera for adding their search bar. Also if you see the bookmarks, there are some inbuild bookmarks and hence these sites will be giving money to opera. I dont like opera, I LOVE IT. Excellent browser
