It doesn't sound like you are a competitor for Pocket. It sounds like you are a competitor to Diigo. You might want to re-evaluate who your competitors are and do a SWOT analysis of them.
thanks for the tip. diigo is definitely a competitor (was noticed by our analysis a long time ago but attention to it has fell by the wayside). pocket seems like the biggest whale, so naturally have pinned it as one of our competitors. i think any save-for-later app that introduces discoverability is a competitor
