I've created a webapp using flask which allows you to visit any Steem user's website just by entering their name, after they set their url in their account's metadata:
unlock <password>
update_account_meta <account_name> "{\"url\":\"\"}" true
NB: the escape characters are necessary since the whole JSON structure is interpreted as a string.
This can be used to redirect to any url, but it will not work if the user hasn't set one, or if it's not accessible through http.
I've deployed it at my seed's website: http://seed.zapto.org/<username> but I might be the only person currently with the metadata set to contain a url, and I just redirect to my own seed website.
I encourage you to set your own metadata, and try it with your friends!
