I don't mean to troll, but having ideas is nothing. Of course projects start with ideas but if the creator of the idea didn't pursue given concept - neither should you.

If I cam e up with "Twitter for cats", but with nothing dwscribing why this was a good idea, or what form it might take (mockups? detail on how it would differ from twitter, or how it would be the same as twitter in a way relevant to cats). those details are the value, and that's what's needed. One line descriptions are far from 'part implemented' - they're not even fully thought-out. A paragraph at least would be better...
then they'd be fit to steal ;-)
Also, if an idea implies considerable implementation (twitter impl is known, but still a large task) it has a higher bar to realise (obv.).
If the impl is somewhat unknown or novel, it also has to be fleshed out more e.g. a POC if it is uncertain if it is possible, or if there are significant barriers that might have prevented it existing already.
