I was invited into it, so I signed up. Looked around and couldn't find a way to make it useful to me
For me, the "now what?" moment was more of "now where are all the people I know and want to work with?" I think Wave is a rare case where the "by invitation only" technique worked against it. To make use of Wave, all the people you want to work with need to be able to sign up. The invitation was an additional hurdle to its adoption.
Lynx is pretty secure
Even Lynx has had security issues. While searching for an example, I found this, which is even better
Somewhat related: These days even the taxi drivers don't know the way any more. It used to be such that you could jump into a taxi, mention the address and off we'd go.
Last time I used a taxi, the driver asked me for directions. Then, when I couldn't provide them, I had to spell out the address for him (he hadn't heard of the street before) so that he could type it into his sat-nav.
Not sure if that's really a problem, but I somehow felt cheated. Isn't it his job to know these things?
