Again, I'm talking about an open source application, not about user contributions.The main benefit of this is be that people can know what your application does, and thus it increases trust in your application.
I don't see any downsides in this for you, unless you want to sell the web application and/or artificially minimise competition.
My go-to has always been Feather, they're genuinely good, sharp, smooth blades.
While they're not European (but Japanese), they also aren't from the US so perhaps the recommendation is within the community's spirit?
Why Not Open Source?
We respect open-source ideals but saw other projects struggle with clutter/inefficiency. We opted for a focused, curated approach to keep the database simple and user-friendly which seems to work exactly as intended based on your and other users' feedback.
I think you're confusing open-source with user-contributed.
I understand from your message why you want to curate data instead of accepting and showing many people's contributions, but not why you wouldn't make the site's code publicly available.
Look, I love me some Jason Statham being overly British and kicking ass for upward two hours while barely making a face, so I'm going to say Jason Statham.
My work is on WhatsApp using several groups to manage info, my landlord set up a WA group and every tenant is required to be in it, my extended family communicates everything through WA groups, my friends and direct family were on Telegram because of me but then Durov's arrest happened and I don't think I can convince them again, I'm cooked LMAO
With?
