I haven't reinstalled ArcMap since the last time my laptop crashed in November, instead using only open, web-based tools. So far, doing juuuust fine.
@aejolene Web-based? Which ones?
@Marshdrifter mapshaper, geojson.io, ogre web client.
@Marshdrifter Not to share maps, no. But for general editing purposes I'm not concerned with the above services (usually my shapes don't even have metadata).
