I put out two podcasts per week, and I use Riverside all the time. I've read some of the other reviews, and I don't understand it because Riverside's already always been 100% stable for me. Every single time it's worked, it's worked for whoever I'm interviewing. If I'm interviewing somebody, it creates these great little magic clips, which are like reels that I can put out.
Occasionally, the interface can be a little bit slow, but I also know it's doing a lot with video, so I can wait three to five seconds here and there. I'm on a Windows PC using Chrome, and it's always been stable. It's mostly been really responsive, with a little bit of sluggishness, but I also understand video can do that. I give it a really great two thumbs up, and I will be using it for a long time.
