After getting involved in the "Guiding principles for Ideas in 2014" thread it occured to me.
Why not have giffgaff deliver a personalised package to each member stating ideas they might be interested in?
This way members get to know and support ideas they'd like which leads to a better experience with giffgaff for them. This could be sent out monthly by email (Like your monthly usage statement) depending on the areas of giffgaff you frequent most often. So if there was a way giffgaff could identify the areas you had been really involved in, such as the 4G consultations, they could possibly send you a link to the idea "4G at no extra cost" which is actually under consideration at the moment. A mock up message could go:
Hello *insert username* at giffgaff we encourage our members to get involved and help giffgaff get better by suggesting ideas. Since you've been involved in *insert activity* we think you might like to support these ideas *insert links to ideas*
Members could opt in by accepting "You're happy to get info and offers from giffgaff" in your contact permissions. Maybe this personalised package could be sent with your monthly usage statement. If giffgaff offered this package to each member the ideas board would really light up and get going. It's possible that ideas that loads of giffgaffers would love are being ignored because they simply don't know about them! So in conclusion:
Every month giffgaff should send out a personalised package to each member with links to ideas they might like to support depending on their recent activity. This message could be included with the monthly usage statement and they could even complement each other if there was a proposal to increase minutes on a certain goodybag or what not.
Thank you for taking your time to read this; I'd really love to hear any awesome ideas or suggestions you guys have about this Thank you to @hazel22 for encouraging me to propose this idea
