I didn't know how bad the security was so I didn't claim this publicly earlier, but I'll do so now that it seems like a general concern. When I was invited to beta, my password was a former title of mine ("Assistant Research Technician"), I held earlier. It was pretty specific, so I was pretty shocked to see it as my password. Also, it didn't work. I finally had them invite me through a different e-mail account and it worked.
Still, how did they get that title, as it didn't seem to be a coincidence? I thought maybe they were scraping information based on our e-mail addresses from the internet. I was told they didn't, then once they figured it out, they said they actually did do this using some third party software (for marketing research, demographic targeting, or what have you). Still, that's pretty ridiculous and insecure. And they must have written their code pretty badly if their scraper replaced a numerical password I was supposed to receive with an incorrect multi-word password based on my identity. I'm not a huge privacy nut, but this is ridiculous, and if this had happened to someone else, I can understand if they would be furious. I was hoping it was an issue on my end with my e-mail client (gmail, so not likely), replacing something in the html code of the e-mail.
