I want to start a blog for my website. Should I use a script or blospot to host my blog? If I should host a script which is a good one?
I would use blogger (blogspot) or wordpress and host it on your site. You can alter the templates to fit your site if you wish.
Personally I would go with wordpress or movable type or something like that would let me have full control. You can edit everything, move from server to server and so on.
I have just launched my first ever blog, its done using blogger and hosted on my site. I altered the template to fit the site and it works very well. Check it out in the latest blog link above.
Go with Wordpress.org. Very easy to use, install, customize, and you can host it on your own server. I've been using it for a year, just upgraded to 2.0, and it's fantastic. You can't get anything this good even if you paid for it (i.e. MT).
What kind of thing do you have in mind for you're blog? I mean, if you just want something easy to get started with then something like blogger or wordpress.com is probably a good idea. Haven't got much experience of this though so I don't have any recommendations. If you want to spend time on the technical side of things (or you like the control) then installing hosting your own blog is going to be the one to go for. Personally, I've only used MoveableType (up to 3.01D) and now I'm using Wordpress 1.5. I prefer wordpress but that might change when the next shiny object comes along...
