Great points. I so agree, after being on here for over two years, if you don't enjoy it, it's not going to be worth it.  It is a fun place to interact  and hang out, that's for sure. 
As for Dtube, I've not gotten on yet, have to figure it out first. Plus, I don't do videos of myself, but I HAVE made others I'd like to put out. Just silly stuff (surprise!), but need to take the time to dig into it.  Does it have much of a learning curve? Particularly for those of us with questionable computer skills?   Suppose it's like jumping off your dock, into the May water, ya just gotta hold your nose with one hand, your trunks with the other, and take the leap.  Deep stuff for a Friday night.  Cheerio(s) my friend.
