Roger, yes I am adding a fair chunk to the sheet but just once. I'll PM you both with a link to my Dropbox when finished, so you can add/subtract from it as you wish. I will also close access to my YT profile (sharing my subscriptions) and delete a few posts to subtract from a few streams of confusion here.
As for linking directly to the
24-digit channel_id/videos vs.
Username/videos, there are a few things going on so let me explain. AFAIK,
channel-id's are permanent but a
user-name can be changed on channel's with
over 100 subscribers (it can grow to over 24 digits too). Linking to a channel playlist's is fine, but these don't always link to video's produced on that channel. (I originally mentioned playlists specifically for channel with mixed content). Since playlists require authors to do channel work to keep actualized, many channel's fall quickly out-of-date, looking sloppy and this gives visitors a dated view hiding gems that may be on that channel (yes visitors can click on video's, but some want it served quick on a silver platter).
Another irritating thing I find about landing on the main page of a channel, is listening over-and-over to some (hope I don't offend..) tactless, plosive and dated channel trailer, seeing the same stuff because the user is too busy making great video's and seldom takes time to update the main page. I'd rather land on the video's page 10-to-1 since by default it shows more thumbnails per page and the newest video's first. There are
search arguments for mixed content channels not producing their own topical playlists, and this is an alternative to playlists, but we talked about that before. (eg: I like Cody'sLab as a channel, but it's not applicable here. However, if I wanted to fish video's with sparse electronics content, we could use arguments like
https://www.youtube.com/user/theCodyReeder/search?query=electronics|arduino|relay ).
(**edit) About me putting-in channel-id's and not names: Would you believe I'm not? (well not really) I'm getting all the URL's produced from my "subscriptions > see all" list in grid-view. That's how YouTube does it, but to save space you can use the channel name (where they exist..).
