@indiescripter I think you've probably got a pretty good start on the IndieWeb philosophy. And an even better start in that you're writing your thoughts on your own website first and then syndicating them to silos like Twitter.
I think that part of what you're missing about being able to reply to Aaron's original post is that his site both sends and accepts a new web protocol known as Webmention (http:/
I know Aaron also often syndicates copies of his posts to Twitter. There's another IndieWeb related service known as Brid.gy which bootstraps webmentions onto Twitter (in addition to other social silos) so that replies or comments to the copy that got syndicated to Twitter also send copies to the original post. In this case, he only syndicated it to news.indieweb.org, so it was less simple for you to have interacted with his post because there wasn't a Twitter version for you to interact with.
You'll find that within the broader community that different members will support varying levels of functionality (based mostly on what they're interested in), so someone like Tantek (tantek.com) will post on his own site and syndicate to Twitter, but he doesn't yet display webmentions. You can, however, post your replies to him on your own site and syndicate them to Twitter (perhaps using Brid.gy publish?) to reply to his syndicated copy on Twitter where he'll see the notification of your reply. You yourself serve as another example as you don't (yet?) offer a comment field on your own post. Perhaps you may never, but that's your choice. (I'll mention incidentally that many static website owners are using Aaron's Webmention.io for sending/receiving webmentions, see also: https:/
I think that a lot of the goal is to not only have fun with what you're doing on your own website, but do things which you find interesting/useful for yourself. Are you interested in locations/check-ins [http:/
Just be careful, because lurking in IRC or browsing the IndieWeb wiki for a while and seeing what others are working on or doing can make you very "itchy". Though the reverse is true that seeing what others have done (even how silos have done things in the past) can make it easier for you to build it not only better, but perhaps more quickly. Perhaps the CMS or language you're using is being used by others in the community [http:/
Keep up the search, and let us know if we can be of further help/assistance.
