Harry stressed that this was a key consideration to him.  As an influential
member of the social web (he was chair of the W3C Social Web XG), I would
consider his opinions important.  His complain was that he raised this
before, and that the webid group did not look at it.

If we, as a group, are able to address such concerns, or show that we have
evaluated them and proven then are non issues (for example in a FAQ), it
may help bring the benefits of WebID to a wider audience.
