We discussed this at the Podcamp Toronto, but I think it's worth discussing here, in this group.
As a vlogger, we spend our time filming, editing and posting our vlogs. We invest our time to our hobby. On the other side of the coin, our viewers also invest their time in watching and commenting. We, as vloggers, bloggers, podcasters have the responsibility to keep producing vlogs or at least tell our viewers why we've stopped or when/if we'll be getting back into it. I know of a bunch of vlogs that I use to follow, but the creator has just stopped. Perhaps they got bored, hit by a bus or maybe it's equipment issues. Regardless what the reason is, I want to know why they've stopped. A simple post would be nice. If you normally do a daily show and then decide you can't keep up with that schedule, then let the viewers know. If you normally post on a Thursday, but you're away for a couple weeks, let your viewers know. If you are going to shelf the whole idea or vlogging, it'd be great if you could recommend other sites your viewers could visit instead. If you are a vlogger and have come into a creative block, let your users know. "You know, I just don't feel like doing a show this week, so instead I'd like to offer you a best-of show". A change of scenery might be all that it takes. If you have a vlog about horror movies and you're tired of talking about slashers, maybe you could start talking about chick-flicks or other genre. Heck, even Star Trek had spin offs. Anyhow... just remember that the time you, as a vlogger, are investing in creation, there are others who are also investing their time in watching.
