Today left me wondering if conference backchannels are still a thing and whether organisers need to start organising/designing backchannels to make it useful (again).

I was at the FOSS4GNL conference today, the first large scale event I went to since the Dutch start of the Situation mid March 2020. Or largish event, because there were about 60% of the usual amount of people, with some staying away because they felt uncomfortable in groups, or because of not wanting to submit themselves to QR code scans to verify vaccination or testing status, and a presenter testing positive the day before.

In the run-up I added the conference # to my Tweetdeck columns and mobile Twitter app. Yesterday was a workshop day, and today a conference day, and the 101 participants posted all of 45 tweets during the event. That works out to about .4 tweets per participant and 2 to 3 tweets per tweeting participant. Back in the day ™, aka 2006, I remember how Twitter started replacing IRC as a conference backchannel of the more geeky conferences I went to. A decade later, when visiting the global conference of the Dutch local one I visited today, FOSS4G global in 2016, I was happily surprised to see IRC even used as backchannel.

This time around there’s wasn’t much of a backchannel, not publicly on Twitter, but also not in some other channel. The conference organisers had used a Telegram group for their preparatory work, and beforehand suggested participants to use that as well. That didn’t pan out I think. I don’t use Telegram and wouldn’t install it for a conference either. The organising membership organisations and the QGIS-NL user group themselves use a Matrix channel, which I think would have been a much better suggestion as at least community members are familiar with it, and it allows a variety of clients to tap into it.

To me backchannels, and I’m spoilt ’cause Reboot (again: back in the day ™), allow one to be in one track of the conference and follow along with the sessions in other tracks to get the salient bits or know when something out of the ordinary happens because one of the rooms ‘explodes’. This works very well, up to the point where I may well think I remember noteworthy conference sessions, while in reality I wasn’t in the room where myths originated but followed along from the next conference room on IRC.

I dislike conferences where members in the audience are just that, and don’t behave like participants. Backchannels allow you to build connections with others based on content or wit during sessions, not relegating it only to random encounters over coffee or lunch (which is also useful). In events like today where it is primarily a community meeting, that is even more true despite everyone being in a more known environment: I’m a lurker/boundary spanner in the Dutch FOSS4G community, have visited/spoken at their events, have organised related events, but am nowhere near the core of community members, yet I knew some 1 in 10 today and a similar number of ‘colleagues of’, including the international participants.

Twitter definitely isn’t the ‘great equalizer’ of backchannels as it has been for a decade or so any more. In the past few years I saw how the use of Twitter as backchannel diminished already, now at the first event I visit after All This it stands out once more. I don’t see something else naturally taking its place either.

In short I miss well-functioning backchannels. Do others miss them, or never knew to miss them?
If you (like I am at times) are an event organiser, is it necessary to plan ahead for a ‘back-channel experience‘ taking into account accessibility, avoiding silo’s and tracking, with which to add to what it is like to attend your event? Or will the idea of a back-channel be let go entirely, reducing all of us to more singular members of an audience?

Vandaag vond FOSS4G-NL plaats, de eerste grote bijeenkomst waar ik weer heen ging.

Ik gaf een presentatie over de aankomende EU wetgeving t.a.v. digitalisering en data, en de kansen die daarin liggen voor de free and open source software for geo community (FOSS4G). Drie jaar geleden sprak ik tijdens de opening van FOSS4G-NL over de geopolitieke rol van data, dat Europa daar een andere koers ging kiezen dan bijvoorbeeld de VS (maximale winst-extractie) en China (maximale staatscontrole), namelijk een waar maatschappelijke waarde in lijn wordt gebracht met het versterken en beschermen van burgerrechten, en dat iedere lokale geodata-adviseur een geopolitieke actor daarbinnen is.

Dit jaar kon ik daar concreet over verder praten omdat de Europese Commissie een reeks wetgeving heeft voorgesteld die invulling geeft aan die geopolitieke propositie t.a.v. data. In die praktische invulling, die vooral nog moet gaan gebeuren, liggen kansen voor de FOSS community en FOSS4G community omdat juist hun kennis t.a.v. federatie, standaarden, en het accomoderen van heel verschillende belangen en perspectieven de dagelijkse gang van zaken is.

Dank aan de organisatoren om weer een FOSS4GNL te organiseren, en fijn om weer in Enschede en bij het ITC te zijn.

I’m at FOSS4G-NL today, the Dutch annual meet-up of the FOSS4G community. This morning I gave the opening keynote titled “A map is the greatest of all epic poems“, and talked about how data is a matter of geopolitics and ethics by design, even if you’re a geo-data pro somewhere in a small municipality working on some hyperlocal data set. The invitation came as a result of my keynote at the global FOSS4G conference in Germany 2 years ago. Slides in Dutch can be downloaded at and are embedded below. Will post a transcript in English later.
