I would like to question the virtual/online nature of a collaborative infrastructure as joseph has written about in the sketch. In India, and from my reading even in some other countries of the Global South, the virtual/online mode itself creates access barriers and is exclusive because of issues such as the failure of electricity, internet connectivity, even lack of network coverage in remote rural regions. Moreover, even in regions with good network coverage and access to electricity, a significant fraction of the population doesn't have the required minimum education to be able to leverage upon the online infrastructure platforms such as emails. I agree with Joesph's conceptualisation of collaborative infrastructure, but in my opinion, it may also be beyond the virtual world, for instance, a Self-Help Group (SHG) of women in a village supporting one-another in times of distress.
I would also like to continue leveraging upon and contributing to the collaborative infrastructure as Joseph has discussed for himself through the virtual collaborative infrastructures.
I had not thought of apps or software/tools as collaborative infrastructure earlier. However, reading Joesph's sketch I am able to visualise several other collaborative infrastructures in my vicinity. The idea of sharing work/responsibilities in a collaborative infrastructure is also quite insightful for me.
