I think that depends on your definition of collaboration. I am always interested and willing to collaborate with anyone on this forum by providing referrals, advice, and information and most members that I had gotten in contact with on here have the mindset. Information is freely exchanged on this forum and any questions I have seen posted get replies very quickly.
If by collaboration; you mean entering into joint ventures; then I have not personally been involved in a joint venture with someone off this forum but I have heard of others who had done so. It's possible to find people with funds to collaborate with on here if you have a good that that's been verified but I don't think you would find too many people who are willing to jump into something like that based off one forum post. Once there is actual capital on the line; people typically collaborate with people that they know and trust. Those two factors take time to build and are not likely to be developed from a forum post or two.
If there are specific questions you have or a specific collaboration you are looking for; then I encourage you to post it on here. Many on here, including myself, are always interested in new collaborative opportunities.
