I'd like to share with you my "weekend" project - LStack (http://lstack.com/), simple web application built as a by-product of another project I'm working on (on which I've tried to get HN feedback few weeks ago - see http://news.ycombinator.com/item?id=3194597).

LStack was born of frustration with one specific limitation of other bookmarking apps (like Delicious). I'm doing a lot of research for my projects and I needed to store some attributes about bookmarked articles, companies, webapps, courses and certifications info, etc. My tags, plain text description fields, notes were becoming a mess.

I needed my bookmarks annotated with parameters like "price = 100 USD", "integrated with = facebook", "integrated with = twitter", "filetype = pdf", "filetype = doc", "funding = 1M USD", "prep = gmat", "prep = lstat", "payments = paypal", "payments = credit card", "type = news", "type = company", "type = product", "contact email = [email protected]", "supported language = english", "stage = private beta", etc.

So about month ago I've spent few days to implement LStack which allows me to save not only bookmark but also additional "structured" data connected with it. The webapp is still very raw and not even close to feature-rich predecessors like Pinboard or Delicious, but I've successfully switched to it and extensively use the unique smart tags feature.

What do you think of the application? Do you face similar problem? Do you find the webapp useful? I'm wondering if anybody could be interested in additional, especially "premium" (paid) features. Do you think something like LStack has a chance to become a business, not just hobby side-project?

Best regards, Seele
