Social geolocation services over the years have been very useful for me. The value is in triggering serendipitous meetings: being in a city outside my normal patterns at the same time someone in (or peripheral to) my network is in the city too, outside their normal patterns. It happened infrequently, about once a year, but frequently enough to be useful and keep checking in. I was a heavy user of Plazes and Dopplr, both long since disappeared. As with other social platforms I and my data quickly became the marketable product, instead of the customer. So ultimately I stopped using Foursquare/Swarm much, only occasionally for international travel, and completely in 2016. Yet I still long for that serendipitous effect, so I am looking to make my location and/or travel plans available, for selected readers, through this site.
There are basically three ways in which I could do that.
1) The POSSE way. I post my location or travel plan on this blog, and it gets shared to platforms like Foursquare, and through RSS. I would need to be able to show these postings only to my followers/ readers, and have a password protected RSS feed and subscription workflow.
2) The PESOS way. I use an existing platform to create my check-ins, like Foursquare, and share that back to my blog. Where it is only accessible for followers/readers, and has a password protected rss feed.
3) The ‘just my’ way. I use only my blog to create check-ins and share them selectively with followers and readers, and have a password protected rss feed for it.
Option 3 is the one that provides the most control over my data, but likely limits the way in which I can allow others to follow me, and needs a flexible on-the-go way to add check-ins through mobile.
Option 2 is the one that comes with easy mobile apps, allows followers to use their own platform apps to do so, as well as through my site.
Option 1 is the one that is in between those two. It has the problems of option 3, but still allows others to use their own platforms like in option 2.
I decided to try and do both Option 2, and Option 3. If I can find a way to make Option 3 work well, getting to Option 1 is an extension of it.
Option 2 at first glance was the easiest to create. This because Aaron Parecki already created ‘Own Your Swarm‘ (OYS) which is a bridge between my existing Foursquare/Swarm account and Micropub, an open protocol for which my site has an endpoint. It means I can let OYS talk both to my Swarm account and my site, so that it posts something to this blog every time I check-in in Swarm on my mobile. OYS not just posts the check-ins but also keeps an eye on my Swarm check-ins, so that when there are comments or likes, they too get reflected to my blog.
My blog uses the Posts Kinds plugin, that has a posting type for check-ins, so they get their own presentation in the blog. OYS allows me to automatically tag what it posts, which gets matched to the existing categories and tags in my blog.
I from now on use a separate category for location related postings, called plazes. Plazes was the original geolocation app I started using in 2004, when co-founder Felix Petersen showed it to me on the very first BlogWalk I co-organised in the Netherlands. Plazes also was the first app to quickly show me the value of creating serendipitous meetings. So as an expression of geo-serendipic (serendipity-epic?) nostalgia, I named the postings category after it.



Jaiku takes presence a step further than Plazes. Where Plazes focusses on geographic location, and presenting information on net access, contacts, and photos around that, Jaiku aims to generate a continuous presence stream, or ‘chatter’. It takes your different RSS feeds, accepts SMS messages, and blurbs you enter on the site, and combines them into one stream. This allows your contacts to be peripherally aware of what you are up to, and estimate the chance and desireability of meeting up. Perhaps not something to publicly share, but again a good example not of having mobile access to information on the web, but of bringing mobile information to the web around your person. The information you share can of course be accessed by others both on the web, as well as on a mobile client.
Imity is yet another angle on presence awareness. It builds on bluetooth signature detection. It allows for you to see who is in the area, or if a friend perhaps just passed through the same location. I first got a glimpse of Imity during this years Reboot conference (see
