It has 17 characters and Nobody searches for 'Welcome to Internet', it is not a keyword domain. Undeveloped, it does not has much value IMHO. You should develop it.
Developed, it depends on how well you develop it. IMO, you could make something like http://www.internet101.org/
difficult to use or develop since "welcome to THE internet" is proper...it's best to attempt to just sell or drop this one.
