They've put together a very comprehensive list of places to post your startup, and some will certainly be relevant to just side projects etc. Depending on what you're looking to showcase. This will certainly be one source I'll look to, for what I launch my side project.
In addition, http://reddit.com/r/financialindependence does a weekly self-promotion thread which has been a nice little bump in traffic.

I will say that It's been a valuable exercise to e-mail every unsubscriber and ask why they left.
The number one reason people leave is because they don't want to get an e-mail every day. We now offer a weekly recap email because of this feedback, and I've actually had people return to the list who had previously left.
Sending an e-mail to someone is a privilege. Especially a daily e-mail. In my opinion our time/attention is one of the most precious things we have.
I want the reader to be able to read and comprehend the opportunity in under 30 seconds and leave feeling like the e-mail had a positive impact on their day.
If you're looking for any advice in specific, get in touch, I'm always happy to help :)
I'll give it a chance as-is but I wonder if weekly emails would be a nice option for some people.
We now have a weekly option! In one of our e-mails click "update my preferences" and then check "weekly".
Just email me - cory@oppsdaily.com, and we can post it for the list!
