Spark Friends having to cut way back on Spark Time due to LACK of time. I have learned to utilize the "feed" on each friend's Spark Page to quickly reply with "Like" and "Comment". I can quickly provide several replies and find where I left off on a previous day.
I routinely go straight thru my Spark Friends either from top to bottom or bottom to top. I find it much faster that going to the Friends Feed. Also if I have to log out, I haven't lost my place in connecting with individuals. On the Friends Feed you have to start from the top AGAIN.
