Do You think .uk , .website , .space , .site Domains are Worth having them??

As long as the domain names are relevant to the extension, then yes there will be interested people.
Ideally brand-able single words.

Don't expect a great price.

i like .uk, but make sure you have .co.uk and .org.uk of the given domain name, or someone else can control your .uk domain. :D

cheers

So if I have a .uk domain and not it's corresponding .co.uk , that will be a problem?

i have heard people share their experience about this, most of them told me to reserve .co.uk and .org.uk to prevent someone to control your domain when it comes to .uk domains. Rest consider it surfing tor without proper security.

Also, I found this interesting set of rules on this page, which explains the complexity of registering a .uk domain
http://registrars.nominet.org.uk/namespace/uk/launch/q-and-a#faq-id-691
Says that if you have a .co.uk or .org.uk, the corresponding .uk will be reserved for you.
And seems like you need a UK address for it as well.

Yes you need a physical UK address. The .uk's are not popular at the moment. They may take off, but for now the interest is low. So its either selling a .uk that matches a current .co.uk (for which they probably have the rights anyway) or it is selling to a domain investor (who will need to wait and take a bet on there being more public awareness and demand in the future).

To answer the original question. I agree with @deez007. In my opinion, all the TLDs mentioned are worth having but as always it depends on the left hand side of the dot. If the LHS complements the RHS then it can be very powerful.
