Why is Sphere making such advertizements?
They should grab the big chance with #deletefacebook and make their advantages very clear.

Can just agree. This now is the chance to promote Sphere in s big way on other social media with the #deletefacebook movement currently going on. They could promote Sphere now through spreading the word with this hashtag, but as there are no informations giving here on the ANN since weeks now I am not sure what the devs currently sre up to.
that's what I've been saying as well. it would be a damn shame for them to lose this opportunity.
Do you know if they are currently doing any big promotions except for these pretty random advertisements?
I don't see any. Not even here in the forum ...
And this is not good.
It can mean, that devs dont care about their project -> this creates the suspicion of scam
or it can mean, that they are not capable to use the #deletefacebook chance to be more well known.
Of course, it is the strong point of the project and should strive to promote it more.
