Question from a confused but willing noob
I'm new to this forum having only just registered a few hours ago but I have spent the last week or so reading up on things here. There is a wealth of knowledge here that I appreciate but as a complete beginner it is quite frankly very confusing at times.
I'm looking to start a blog/blogs as I have a few ideas. These ideas are genuine interests that I already have good working knowledge of. From this I have a few questions to ask, any answers/input would be very much appreciated

i) Does a blog generally need to be based around one subject area or could I mix it with a few other areas of interest? Would this make it messy and unspecific? If so, should I register different blogs for different subject areas?
ii) Are there any "all-in-one" sites that you would recommend for domain registration and blog setup. I'm not the most technical of individuals, I'm hoping my creative abilities in writing make up for some of this!
I know it's going to be a long journey but I'm quite excited by it all and very much ready to put a lot of effort in.
Thanks in advance guys!
