I had a quick look - photography is patchy, and while some of the pictures are excellent there's quite a few phone images with commensurate qualities (iPhone images over-processed, some others just lacking detail). Searching is very hit & miss - 'drama' produced lots of cat pictures. Searching for specific places didn't produce images of those places, but did show other quite un-connected locations from across the world.
If it's new then it *might* be interesting to be part stage of a new and expanding community, but OTOH I'd suggest knowing what you want from it (hosting - do they offer that? showing a portfolio to potential clients? simply a place online to dump your pictures?).
Just a few thoughts at first glance.
Since I asked about it on here, I've signed up to it, but not uploaded anything.
My experience was different to yours, I found the search OK.
Searching for Drama, although it initially brings up some pictures of cats, the list of sub categories along the top of the picture display seem to be accurate when selected e.g. Theatrical masks, stage curtains etc
Additionally, all the places I searched also seemed reasonably accurate. e.g Cornwall, seemed to largely Cornwall, but with a some "Cornwall like" images from seaside place in the UK.
Overall, I thought the quality mix was as good as Flikr and when they introduced albums or "series" as they call it, this was enough for me to decide to give it a go There were enough interesting photographers on it to keep me browsing. Many, seem to have restricted their photographs to members only.
As the user can control visibility, you could make individual series public, and use this as a limited portfolio site, as well as a regular photo sharing site. They suggest uploading your files in full resolution and P3 to maximise the quality seen by the viewer. I haven't tried to assess how the quality compares with Flikr.
I also felt the two guys from the Netherlands who set it up, have a genuine interest in turning it into a very good photographer focussed platform. There is a lot of emphasis on building the user "community", and they have avoided any "external" financial support, to keep control over their decision making.
But I also don't have a big requirement for it, I just want somewhere that I can (quickly) dump a few photographs that I can link to for people to see. The presentation feels cleaner to me than Flikr, and it's less expensive.
The final decider for me, was the availability of an uploader plugin for Capture One. (they also have one for Lightroom) because, above all I wanted something "easy" to use.
Could be worth checking out.
