whats the difference between arweave and ipfs? why choose one over the other?

IPFS is a file sharing protocol, Arweave is a tokenized storage solution (Filecoin is the attempt to tokenize IPFS). Arweave has a goal of making content permanent, whereas IPFS is just a protocol that gives you the option to persist content or not (but Filecoin could be used to make it more archival).

But of course I am biased; take my opinions as such ;)

I think both can have their place but they work totally differently. IPFS can be run by yourself or by a provider; it’s open software peer to peer software like torrent (but better). It can be run by individuals or by services (@pinatacloud). Arweave and its fate is tied to a token, which is good & bad imo
