I think blip need to introduce an app that let's you know "if you carry on posting a blip every day your 300th blip will fall on 9th June". (Obviously substitute appropriate blipversary and date as appropriate).
That way you wouldn't give yourself a day full of appointments giving you no time to think about what on earth to do to mark the occasion.
So here you have it!
3 gerbera's to celebrate 300 blips!
This place and the people here are just great - and each blipversary seems to bring more adventures on my photography journey - so who knows what will happen over the next 65!
Bring it on!
