Show HN: The simplest way to curate Tweets (hashfav.com)

Yes but the reply Tweet doesn't have to be limited to the HashFav tag; it can be embedded in the reply similar to the hashtag (e.g. "wow, this is ##cool"). Replying to the Tweet also serves to notify the author. However if you want to be stealth, you can copy-paste the URL to add a Tweet into a collection.

You might be interested in http://www.tweetd.com/. It extracts links you tweeted and presents them in a easy to use style.

Think of it as your link blog,

for example http://girishso.tweetd.com
