Inspired by https://steemit.com/namecoin/@dantheman/dns-via-steem
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:
From cli_wallet:
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.
Test it out:
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!
