it depends to the owner, if they don't use a dedicated server they will either share a dedicated server.
Which one they use most, I really can't say… To each his own I guess.
all I know, you need to spend a bit of money and have a good server if you want your site to be functioning when there's a lot of traffic.
Very interesting. There's quite a large jump up from $29.99 per month to $175 per month. I wonder at how many active members surfing each day the $29.99 shared server starts getting overloaded.
