<human>: Can you provide a brief overview of the text?

I interviewed for a job as a moderator for a start-up website in NYC. The website was down the day prior and the day of my interview so I wasn't able to really play around with it.

After my lengthy interview I sent a thank you email. I didn't hear anything back but I decided to sign up for the website and give some feedback. A week later I sent my interviewer a decent sized email about things I liked and areas I thought could be improved.

I never received a response but I did notice that there was a poll asking about one of my suggestions and the general consensus was very favorable. I thought this was very odd because I never heard back from them until the other day (weeks later) stating that I did not get the job.

I somewhat felt that the interviewer might have just taken my ideas and presented them as her own? Is that common? Should I just continue to brush it off and move on because I feel that I am not really in a position to do anything. Just felt that it was somewhat messed up.
<bot>: Should I do anything? I submitted some ideas about a website after a job interview. Didn't get the job but they appear to be entertaining one of my ideas.
