Hello @saqimtiaz,
Your plugin is amazing, this is so much better than the hack I was using until now ! I’m particularly excited about the RSS support this will bring to TW 
I wanted that for my blog for a long time and while fraidycat is unbelievably cool it’s not the best solution, especially for big wikis. I know that there already is a solution for that but nothing that is really automatic.
I have some suggestions (for the GitHub part of the plugin) :
- Allowing the user to write a commit message when saving to github for better backup management
- A link to the github page in the plugin settings to quickly go to the online version of the wiki
I use that in my hack and find that while simple, these are a nice addition for the user experience 
I also have a question : my understanding is that this plugin will eventually allow uploading individual tiddlers to GitHub from a single file, static tiddlywiki, without uploading the whole wiki. Is that correct ?
Would it be possible then to have Tiddlywiki lazy load tiddlers from GitHub to a single-file Tiddlywiki ? Because the one thing I’m afraid with using Tiddlywiki as a heavy sized website/blog, is the loading time…
If this is indeed the end goal, then I can see TW becoming a serious contender to WordPress !
Another thing that would be great is the possibility to use the upload plugin locally. I know that the upcoming version of TW will support drag and dropping image into tiddler, which is great, but it imports the images in the wiki itself. The upload plugin would allow to save the image in a local folder instead and link it inside a tiddler to keep the wiki light, which would be awesome for image-heavy wiki (manual, student notebook, etc).
Regarding the founding of TW, how about the blender model ? They also work on a donation basis + have corporate backers
