My thoughts on them.
1. Without personal information, I question how effective interventions can be in high risk cases. If something does go wrong (e.g., the person identifies suicidal or homicidal risk), I would not want to be part of any service where I am unable to take all needed steps to keep someone safe. The ability to have services that focus on provision using the internet does not need to be like this, in my mind. Tele-medicine can open all sorts of doors for readily available service using qualified professionals in rural, under-serviced areas. This is difficult with anonymous services in my mind.
2. There is some emphasis on making sure those talking to the individuals (those that I assume are in need of actual clinical services) are working to minimize harm. Risk occurs when people are not able to give good, scientifically based support (note, not advice on scientific practice but training on rapport and support). It is also a problem when they are not aware of the potential pit-falls, such as their own reactance. An intention to do good is not a guarantee that it will be done. It concerns me whenever someone without training is working with someone with actual need. As with any suicide line or what-have-you, I would be curious to know more about the training models that the folks are getting to help make sure they are providing strong supports with minimal risks. With CEU's as bad as they are, I suspect not all training is up to snuff.
3. I'm all about the idea of increased social support networks as well as wider utilization of the internet as a medium for doing so. I dislike calling that services "counseling". That does a disservice to the public because it conflates what psychology does by emphasizing EST/EBP with non-directive support, which is what these sites offer from all that I've ever seen.
If you are interested in getting involved in something, I would encourage something with a physical space and location.
