Thanks @apm for setting up this panel. Encouraging more participation here is good!
I am also a Google+ refuge. I have an active photo site and a blog but I also like the interaction on a platform like Cake. Like @Glenn_Smith I wanted to keep some of the community feeling that I found on Google+ - but honestly, that feeling has been fading from G+ for quite a while. From what I've seen so far on Cake I think we have the potential of continuing good interactions here.
The latest conversation I posted here was about the Orchid Extravaganza at Longwood Gardens. I wanted to share some of my favorite photos from the visit, and I also wanted to have a conversation with others who are also interested in orchids. I was delighted when @Vilen added photos of orchids that he and his girlfriend have in the "kitchen garden". Interaction with others makes the conversation flow and keeps it interesting.
While my focus in the conversations I've started (so far) has been photography plus some travel, I always try to write about the experience too. My photo galleries are the home of a full set of chosen photos from the activity, my blog and Cake conversations contain words too.
Here's a link to the full photo gallery from my Longwood Gardens visit to show the difference.
I agree with @Glenn_Smith that it is good to pose a question in your conversation to encourage others to join in.
I like seeing reactions since it lets me know that people are viewing my conversations but I really value the interactions in words that are possible here. Multi-person conversations are more interesting...
Don't hesitate to add your comments to conversations that interest you. It's the interaction between people that keeps the conversations alive.
